Introduction

Stepping into the Pantheon is like diving into eternal Rome. The largest unreinforced concrete dome in the world leaves you speechless, and the oculus above seems like a divine eye watching over everything. It makes you feel small, but in a good way. No photo can capture the effect: the constantly changing light creates a unique atmosphere. And to think it’s almost 2,000 years old…

Historical Notes

The Pantheon was built in 27 BC by Marcus Vipsanius Agrippa, son-in-law of Augustus, as a temple dedicated to all pagan gods. After two fires, Emperor Hadrian rebuilt it between 118 and 125 AD, giving it the form we see today. In 609 AD, Emperor Phocas donated it to Pope Boniface IV, who consecrated it as a Christian basilica (Santa Maria ad Martyres), saving it from destruction. Since then, it has always been in use, an almost unique record.

Dome and Light: An Engineering Masterpiece

The dome is a technical marvel. It is made of concrete with increasingly lighter materials toward the top – from travertine to pumice – to reduce weight. The 28 coffers per row are not just decorative: they reduce mass. The 9-meter oculus is the only source of light, and when it rains, water enters but is drained through holes in the slightly convex floor. On April 21, the anniversary of Rome, a sunbeam perfectly illuminates the entrance.

Famous Tombs and Legends

Here lie Raphael (with the famous epitaph by Pietro Bembo), the kings of Italy Victor Emmanuel II and Umberto I with Queen Margherita, and other artists. A tradition says that during the Christian consecration seven demons fled through the oculus. Pope Urban VIII had the bronze of the portico melted down for the baldachin of St. Peter’s, giving rise to the saying: “What the barbarians did not do, the Barberini did.” Every year at Pentecost, a rain of red petals falls from the oculus.

Why Visit It

1. It’s the best-preserved ancient building in Rome: you walk where emperors and artists walked. 2. The dome is an icon of world architecture, surpassed in size only in modern times. 3. Entry costs only €5 (reduced to €2 for ages 18-25, free for under 18 and on the first Sunday of the month), a trivial price for a millennial masterpiece. Moreover, as it is an active church, you can also attend religious services.

When to Visit

The most magical time is shortly before closing, around 6:00 PM, when the low sun enters through the oculus and lights up the dome with warm colors. In summer, the nearly vertical rays create a perfect bright disk at the center of the floor. If you can, choose a day with light rain: you’ll see water fall from the oculus and disappear into the holes, a rare sight.
