What to see in Siena: 15 stops from the Cathedral to the Medici Fortress

Arriving at Il Campo is a sight you'll never forget. It's not just a square, but a shell-shaped amphitheater of red bricks that gently slopes down towards the Palazzo Pubblico. It welcomes you with that natural incline that feels like an embrace, and you immediately understand why the Sienese simply call it 'Il Campo' – as if no other existed in the world. The sensation is that of entering an open-air living room, where people sit on the warm bricks, chat, and observe. At its center, the Fonte Gaia with its Renaissance sculptures replaces the original 14th-century one, but remains an unmissable meeting point. Looking up, the Torre del Mangia soars with its 88 meters: climbing it requires some breath (there are 400 narrow steps), but the view over Siena and the Tuscan hills rewards every effort. Beneath the tower, the Palazzo Pubblico houses incredibly rich museums, with frescoes like Ambrogio Lorenzetti's Good Government that help you understand the city's history. Il Campo lives two lives: the daily quiet and the fever of the Palio, which twice a year transforms the square into a dirt track where horses race at breakneck speed. Even without the Palio, the atmosphere is magical: in the evening, lights illuminate the bricks and the cafes fill with voices. A tip? Have a coffee at one of the bars with outdoor tables and look around: every corner tells centuries of history, of rivalries between contrade, of life flowing slowly and intensely. It's a place where you gladly lose yourself.

If you think you've seen everything in Siena, think again. The Cathedral of Santa Maria Assunta, with its black and white striped facade, is a sight you won't easily forget. As soon as you enter, a solemn atmosphere welcomes you, but it's the polychrome marble floor that steals the show: 56 panels tell sacred and secular stories, a true carpet of art that is only revealed during certain periods of the year. I happened to see it during the special opening in September, and I assure you it's worth planning your visit for those days. Don't just look up: details are everywhere, from the twisted columns of Nicola Pisano's pulpit to the floor mosaics that look like paintings. One thing that struck me? The Piccolomini Library, frescoed by Pinturicchio with scenes from the life of Pius II – those bright colors transport you to another world. And then there's the Baptistery, often overlooked, but with Donatello's baptismal font that is a Renaissance jewel. Note: climbing to the Porta del Cielo, the panoramic terrace, requires a separate ticket and some breath, but the view of Siena and the Tuscan hills rewards every step. Some practical advice? Buy the combined ticket online to avoid lines, and dedicate at least an hour to it, although I lost half a day there between photos and contemplation. If you're lucky, you might attend an organ concert – the acoustics under those vaults are magical.

If there's one spot where Siena reveals all its beauty, it's from the top of the Torre del Mangia. The climb is challenging—a full 400 steps with no elevator—but the effort is rewarded as soon as you reach the summit. From up there, your gaze sweeps over the red rooftops of the historic center, the Piazza del Campo that looks like a seashell, and the gentle Tuscan hills surrounding the city. The tower, standing 88 meters tall, was built between 1325 and 1348 and takes its name from its first bell-ringer, Giovanni di Balduccio, nicknamed 'Mangiaguadagni' for his habit of squandering his salary. A fun fact that made me smile: the tower was designed to be as tall as the Duomo's bell tower, symbolizing the balance between religious and civil power. Today, climbing it is almost a must-do experience for anyone visiting Siena. Be aware, though: access is regulated by timed slots and the number of visitors is limited, so it's best to book or arrive early, especially on weekends. Once you've descended, don't miss the Cappella di Piazza at its base, a small Gothic gem that often goes unnoticed. Personally, I found the view at sunset simply magical, with the sky's colors reflecting off the tiles. A tip? Wear comfortable shoes and prepare for a bit of exertion, but trust me, it's worth it.

If Piazza del Campo is Siena's living room, the Palazzo Pubblico is its beating heart, one that has pulsed for centuries. It's not just a palace, but the symbol of medieval communal government, built between 1297 and 1310 to showcase the might of the Republic of Siena. The façade of stone and brick, with those elegant triple-arched windows, immediately gives you the sense of an important place, but it's upon entering that you truly understand. The Sala del Mappamondo (or Council Hall) leaves you awestruck: here you'll find the majestic Maestà by Simone Martini, a 1315 fresco that is an absolute masterpiece of Sienese Gothic art. The colors, the details of the Madonna's robe, the gold that still shines after seven centuries—it almost feels like you can hear the reverent silence of that era. A little further on, in the Sala della Pace, Ambrogio Lorenzetti's frescoes on Good and Bad Government are a lesson in history and art combined. Looking at them, you see 14th-century Siena, with its lush countryside and orderly city, a political message that still speaks today. Personally, I'm always struck by how these artists managed to blend beauty and propaganda so effectively. Don't forget to look up: the vaulted ceilings and decorations are a feast of details. And if you think it's just a museum, you're mistaken: the municipal offices are still located here, making the palace alive and not merely a relic. A piece of advice? Take your time to observe each room carefully—sometimes the smallest details, like a face in the side frescoes, tell incredible stories. And yes, the view from the Torre del Mangia is spectacular, but the Palazzo Pubblico alone is worth the visit, if only to breathe in the air of a Siena that was once great and still shows it.

If you think Siena's Duomo is already spectacular on its own, wait until you discover what lies behind its back. The Museum of the Metropolitan Opera is a bit like that secret drawer that holds the family jewels: here you'll find the original masterpieces that once adorned the Cathedral, removed for preservation and replaced with copies. The undisputed star is Duccio di Buoninsegna's Maestà, a fourteenth-century polyptych that leaves you breathless with its delicacy and still-vivid colors. It's considered one of the most important paintings of the Italian Middle Ages, and seeing it up close, without crowds pushing you, is a rare privilege. But it's not just about paintings. Climbing the narrow spiral staircase (be careful, it's a bit steep) leads to the Facciatone, the panoramic terrace offering one of the most beautiful views over Siena. From there, the panorama of the historic center and the Tuscan hills is simply unmissable. The museum itself is housed in what was supposed to be the right nave of the "New Duomo," an ambitious project never completed. Walking through these halls makes you feel inside a piece of interrupted history. Personally, I find the contrast between the unfinished grandeur of the building and the fragility of the artworks it houses very evocative. There's also a section with sculptures by Giovanni Pisano and other sacred treasures. I recommend taking your time: every corner holds a surprise, and that final terrace deserves to be enjoyed at a leisurely pace.

If you're looking for a corner of Siena that combines spirituality, history, and art, the Caterinian Basilica of San Domenico is an unmissable stop. It's not just a church, but a place steeped in the presence of Saint Catherine of Siena, the patron saint of Italy, who lived crucial moments of her life here. The basilica, in Gothic style, stands on a hill offering a spectacular view of the historic center and the Duomo – a panorama that alone is worth the visit, especially at sunset. Inside, the atmosphere is austere and intimate, with wide naves and soft lighting that invites silence. Don't miss the Chapel of Saint Catherine, where relics such as the saint's head (a powerful image, I must admit it struck me) and her walking stick are kept. There's also a fresco by Sodoma depicting Catherine's disrobing, a work that captures the intensity of her mysticism. Personally, I was surprised to discover that here you can find the cell where Catherine slept, a small space that makes you feel close to her daily life. The basilica is active, with regular masses, so you might encounter local worshippers in prayer – a detail that adds authenticity. If you visit in spring or summer, take advantage of the attached Renaissance cloister, an oasis of peace with a central well and elegant arches, perfect for a break away from the crowds. Note: admission is free, but check the opening hours as they may vary based on religious functions. This isn't a place to rush through in five minutes: take your time to observe the details, like the colored stained-glass windows and ancient tombstones. For me, it was an unexpected moment of reflection, even though I'm not particularly religious – the history here is palpable, and you breathe a different energy compared to other more touristy monuments.

The Medici Fortress, or Forte di Santa Barbara, is one of those surprises you least expect in the heart of Siena. Built in the mid-16th century at the behest of Cosimo I de' Medici, it's not just a symbol of power, but a living place frequented by locals. Its star-shaped design with angular bastions makes it unmistakable when viewed from above, perhaps from the Torre del Mangia. Entry is free, and you're immediately struck by the vast interior space: a public park where people jog, walk their dogs, or simply sit and chat. The real must-do is walking along the walls: climb onto the ramparts and the view over Siena and the Tuscan hills will take your breath away. You can see the Duomo, the towers, and on clear days, the outlines of Mount Amiata. Personally, I love going there at sunset, when the golden light envelops everything and the atmosphere becomes magical. Inside, there's also the Enoteca Italiana, with a historic cellar where you can taste wines from all over Italy – perfect for a break after your walk. It's not a traditional museum, but a place where you can breathe in history without feeling like you're in a display case. Sometimes there are concerts or summer events, and seeing the fortress lit up at night is a spectacle. If you're passing through Siena, don't miss it: it's a corner of tranquility and beauty that many hurried tourists overlook, yet it's truly worth it.

If you think Siena is only about Piazza del Campo and the Duomo, the Basilica of San Francesco will make you think again. This place, often somewhat overlooked by the more beaten tourist paths, is a surprise worth seeking out. It's located in Piazza San Francesco, a tranquil area just steps from the historic center, but with a completely different atmosphere: less chaotic, more intimate. The exterior building, with red bricks typical of Franciscan Gothic style, seems almost austere, but that's just an initial impression. Once you cross the threshold, you're welcomed by a spacious and bright interior, with a single nave that makes you feel small in the face of its majesty. The sensation is one of immediate peace, far from the crowds. Here, the element that most strikes you are the 14th-century frescoes decorating the walls. Don't expect perfectly preserved works like in a museum: some are faded, others show signs of time, but that's precisely what makes them authentic. They depict scenes from the life of Saint Francis and Christ, with soft colors that tell stories of devotion. Personally, I was struck by the Chapel of the Seven Joys of the Virgin, a side corner where the details seem to almost whisper. There's also an underground crypt, discovered only in the 20th century, which preserves remains of even older frescoes – a true hidden treasure. The basilica also houses the tomb of two Sienese blesseds, a detail that deeply ties it to local history. I recommend taking a look at the adjacent cloister, a silent courtyard perfect for a contemplative break. If you visit Siena, including San Francesco in your itinerary means discovering a more intimate and spiritual side of the city, away from the usual clichés.

If you think Siena's Cathedral is only what you see on the surface, prepare for a surprise. The Baptistery of San Giovanni is located right beneath the cathedral's apse, in a position that almost hides it, like a well-kept secret. Descending those stairs is like entering another dimension: the atmosphere changes instantly, becoming more intimate, almost cozy. The first thing that strikes you are the frescoes on the walls, a Renaissance pictorial cycle that completely envelops you. Artists like Lorenzo di Pietro, known as Vecchietta, and Benvenuto di Giovanni worked here, and it shows. The colors, despite the centuries, retain a surprising vitality. The highlight is undoubtedly the hexagonal baptismal font, a work of art in its own right. Look at it carefully: the bronze panels that decorate it are signed by Donatello, Ghiberti, and Jacopo della Quercia. Donatello's panel, in particular, depicts the Feast of Herod and is a masterpiece of drama. Personally, I lingered on these details for a long time, trying to capture every expression, every movement. The light filtering through the Gothic windows creates suggestive plays of shadow, accentuating the relief of the sculptures. Don't overlook the crypt, accessible from here, with other 13th-century frescoes discovered only recently. It's a place that speaks of history, but also of daily devotion: even today, baptisms are celebrated here. Admission is included in the Duomo complex ticket, but many skip it, distracted by the majesty of the cathedral above. A mistake, in my opinion. It's worth dedicating at least half an hour to it, to savor that silence filled with art.

If you think Siena is only about Piazza del Campo and the Cathedral, prepare to change your mind. The National Picture Gallery is one of those places that truly lets you understand the artistic soul of this city, yet many visitors skip it entirely. That's a shame, because here you can breathe in the history of Sienese painting in an almost intimate way. I stumbled upon it by chance, hidden on the second floor of Palazzo Buonsignori, a medieval building that's worth a visit in itself. Upon entering, you're greeted by a quiet atmosphere, far from the crowds of the more popular tourist routes. The collection is organized chronologically, which is a blessing for those like me who sometimes get lost among names and dates. Start with the 13th-century panels, those with gold backgrounds that seem to glow with their own light, and work your way up to the 17th century, passing through masterpieces from the 14th and 15th centuries. There are works by Duccio di Buoninsegna, Simone Martini, and the Lorenzetti brothers, but also by lesser-known artists who deserve a closer look. For instance, I was struck by the delicacy of Sano di Pietro's paintings, with figures so expressive they almost seem to speak. The layout of the rooms is simple, without too many frills, allowing you to focus on the artworks without distractions. A piece of advice? Don't rush. Some rooms are small, almost cozy, and it's worth pausing to appreciate details like the background landscapes or facial expressions. I noticed that natural light filters through the windows, creating plays of shadows that change with the time of day, making the experience even more evocative. There's also a section dedicated to small-scale panels, perfect for those who love details. I visited on a quiet morning and felt as if I had discovered a hidden treasure. It may not be the most famous museum in Siena, but in my opinion, it's one of the most authentic. If you love art, you can't miss it: it's like flipping through a living art history book, all concentrated in a few rooms.

If you think you've seen everything in Siena, think again. The Basilica of San Clemente in Santa Maria dei Servi is one of those places that escapes the most beaten paths, but it's truly worth seeking out. It's located on a hill just outside the historic center, in a position that offers a breathtaking view of the city and the Tuscan countryside. Getting there is a small adventure: you climb up narrow, quiet streets, away from the crowds of Piazza del Campo, and when you finally see it, you understand why it's called the 'basilica of the Sienese.' The exterior is simple, almost austere, with that brick facade that seems to tell centuries of history. But it's inside that the magic happens. As soon as you cross the threshold, you're immediately struck by the atmosphere: it's a mix of peace and grandeur, with that wooden trussed ceiling that makes you feel both small and protected at the same time. The frescoes are a hidden treasure: take a close look at those by Pietro Lorenzetti in the side chapel, where the colors still seem vibrant despite the centuries. And then there's the altarpiece by Lippo Memmi, a Madonna and Child that has something hypnotic about it. I visited on a sunny day, and the light filtering through the windows created plays of shadow on the walls, making everything even more evocative. It may not be the most famous church in Siena, but in my opinion, it's one of the most authentic. If you want to breathe in the soul of the city without the tourist bustle, this is the right place. A tip? Bring a camera: the view from the churchyard is postcard-perfect, especially at sunset.

If you think you've seen everything in Siena, prepare for a pleasant surprise. The Oratory of San Bernardino and the Diocesan Museum of Sacred Art are one of those places that escape the most beaten paths, yet offer an authentic and intense experience. You find yourself in Piazza San Francesco, right next to the basilica, and the oratory's sober exterior already tells you that here, all attention is focused inside. Upon entering, the first thing that strikes you is the atmosphere: silent, intimate, almost secluded, far from the crowds of the city center. The oratory, dedicated to San Bernardino of Siena, preserves Renaissance frescoes that narrate the saint's life with surprising vibrancy. The colors, despite the centuries, still seem vivid, and the details of the scenes make you linger a few minutes longer than planned. Personally, I stopped to observe the depiction of the preaching in Piazza del Campo: seeing how the artists of the time immortalized Siena in the fifteenth century is a small journey back in time. Then there's the Diocesan Museum, which occupies the adjacent spaces. Don't expect a huge or sprawling museum: here everything is concentrated and well-curated. The works come from churches and convents of the Sienese diocese, giving the visit a profoundly local character. You'll find painted panels, wooden sculptures, sacred vestments, and liturgical objects ranging from the Middle Ages to the eighteenth century. Among them, some works by lesser-known but highly fascinating Sienese artists stand out, like a fourteenth-century wooden crucifix that emanates incredible expressive power. The layout is clear, the labels essential, and the environment well-lit. A tip? Dedicate at least an hour to this complex, because it deserves to be experienced calmly. It's the ideal place for a reflective break during your city visit, especially if you appreciate sacred art without frills. I discovered it almost by chance, and now I always recommend it: it's an important piece for understanding Siena's spirituality and artistic history, beyond the more famous monuments.

If you think Siena is only about the historic center, you're greatly mistaken. Just outside the city walls, on a hill overlooking the city, stands the Basilica dell'Osservanza, a place that offers you another perspective on Siena, both literally and metaphorically. Getting there is an experience in itself: you follow a scenic road that shows you why this area is called 'Colle della Capriola.' The basilica, with its brick and travertine facade, almost seems like a refuge, simple on the outside but incredibly rich inside. Built in the fifteenth century and later reconstructed after the bombings of World War II, it houses artworks that will leave you breathless. Upon entering, the atmosphere is one of palpable quiet, different from the hustle and bustle of the center. The frescoes, the della Robbia terracottas, the inlaid wooden choir... every detail speaks of devotion and artisanal mastery. Personally, I'm always struck by the Chapel of San Bernardino, with its altar that seems sculpted from light. It's a place where you stop, breathe, and observe. It's not just a church; it's a piece of Sienese history that authentically tells the story of Franciscan spirituality. I recommend checking the opening hours before you go, as it can sometimes be closed for services or restorations. And if you have the chance, take advantage of the silence in the adjacent cloister: a perfect corner of peace for a contemplative break.

If you think you've seen everything in Siena, prepare for a surprise. The Siena Synagogue is one of those places that escapes the most beaten tourist paths, but it's definitely worth a visit. It's located in a quiet alley, near Piazza del Campo, and from the outside it could almost go unnoticed – the facade is simple, understated, typical of Italian synagogues that for centuries preferred not to flaunt. But once you cross the threshold, it's another story. The interior, rebuilt in the 19th century after a fire, is a small masterpiece of elegance. The atmosphere is intimate, secluded, far from the chaos of the main streets. What strikes you immediately are the dark wood furnishings, the women's gallery (once reserved for women) and the beautiful Tevah, the pulpit from which the Torah is read. The details are meticulously cared for, from the lamps to the decorations. It's not a huge museum; in fact, you can visit it in less than half an hour, but every corner tells a story. That of the Sienese Jewish community, present in the city since the Middle Ages, with alternating events of integration and periods of ghetto. Walking through the rooms, you breathe in a piece of often forgotten history. Personally, I was surprised to discover that here, until not many decades ago, regular religious services were still held. Today it's more a place of memory and culture, managed with passion. A tip: always check the opening hours before going, because it's not always accessible. And if you get the chance, take advantage of guided tours – sometimes community volunteers share interesting anecdotes, like the one about the small collection of ritual objects on display. It's a dive into a different Siena, one that few know.

If you think Siena is all about medieval palaces and cobblestone alleys, the Botanical Garden will change your mind. This peaceful corner is located right behind the Basilica of San Domenico, a spot many tourists pass by without even noticing. Yet, stepping through the gate is like entering another world: the city noise fades away, replaced by the rustle of leaves and the scent of damp earth. Founded in 1856 as a university garden, it now hosts over 900 plant species, some truly unusual. I was struck by the collection of succulents, with cacti that look like they came straight from a Western movie, and the area dedicated to medicinal plants, where you discover that many herbs used in Sienese tradition grow right here. It's not just a simple park: it's a place of study and conservation, but also of pure beauty. The path winds across different levels, offering unexpected glimpses of the city. From one terrace, you can see the Duomo's bell tower peeking through the trees, an image worth the visit alone. The atmosphere is relaxed, ideal for a break away from the crowds. I encountered few visitors, mostly students or locals coming to read a book in the shade of a centuries-old tree. There's also a tropical greenhouse, small but well-kept, where the air stays warm and humid even in winter. Admission costs just a few euros and opening hours vary with the seasons, so it's best to check beforehand. If you love nature or seek a moment of quiet, this place is a little gem. Don't expect grand Italian-style gardens: here, you breathe a more intimate, almost secret air. Perhaps that's exactly its charm.
