Introduction

The Capo Caccia Lighthouse is not just a lighthouse: it is a giant of light dominating the sea from 186 meters high, one of the most powerful in the Mediterranean. Built in 1864 on the limestone cliff of the promontory, it is a symbol of Alghero. You cannot enter – it’s a military zone – but seeing it from afar is enough to enchant you. At night, its white flash every 5 seconds guides sailors and illuminates the bay. I saw it for the first time at sunset: the white silhouette against the orange sky, the sea crashing below. A spectacle you won’t forget.

Historical Notes

The lighthouse was built in 1864, the same year as the Capo Sandalo lighthouse. Initially it used acetylene, then petroleum vapors, and finally electricity from 1961. The rotating optic with 4-panel Fresnel lenses (built in Paris in 1951) is still in operation, with a 1000W halogen lamp. The last keeper, Luigi Critelli, arrived on December 21, 1994 with his family. He told of strange nocturnal knocking that was never explained. Today it is automated, but its history fascinates. Here are the key moments:

A lighthouse to admire from afar

The structure is a three-story white building with a 24-meter tower, typical of the Italian Civil Engineering style. Protected by a Faraday cage, it appears wrapped in a metal grid. You can’t enter, but the scenic road from Alghero leads to a hill behind it offering a breathtaking view: the cliff plunging into the sea, the Coral Riviera, and Isola Piana. I visited with a drone – it’s the best way to appreciate its position. At night, its beam is visible from the city, a landmark that makes you feel small.

Legends and Traditions

The promontory of Capo Caccia is shrouded in tales of pirates and hidden treasures. It is said that corsairs once took refuge in the caves below, and that some chest may still be there. Then there’s the ‘sleeping giant’: the profile of the promontory seen from Alghero resembles a reclining man, especially evocative at sunset. The lighthouse itself has a mysterious atmosphere. The keeper, Critelli, recounted hearing knocking and voices while resting, but upon waking found no one. Who knows if these are true stories or just the wind playing tricks…

Why Visit

Three good reasons not to miss it:

Picture-perfect sunset: The lighthouse lights up exactly at sunset, creating a stunning contrast between artificial and natural light.
Unique viewpoint: Even if you don’t go inside, the view from the road or the sea is spectacular, with Alghero and Porto Conte bay in the background.
Close to Neptune’s Grotto: After admiring the lighthouse, you can descend the 654 steps of the Cabirol staircase to visit one of Italy’s most famous sea caves.

When to Go

The best time? Late afternoon, around 5-6 PM in summer, when the sun starts to set. The golden light illuminates the cliff, and the lighthouse stands out against the sky. Then, as evening falls, you see the first white flash: it’s magical. Throughout the year, spring and autumn offer clear skies and fewer crowds. If you go in summer, expect heat but also very long sunsets. Bring binoculars or a telephoto lens, because from afar the lighthouse is small but powerful.

Nearby

In addition to the lighthouse, the promontory offers two unmissable experiences.

Neptune’s Grotto: accessible by sea or via the spectacular Cabirol staircase (654 steps carved into the rock). Inside, stalactites and underground lakes.
Capo Caccia – Isola Piana Marine Reserve: perfect for snorkeling and diving, with red coral and rich marine life.

Both places are easily reachable from Alghero and complete a day of sea and nature.

💡 Did You Know…?
Among the stories that surround the lighthouse is one told by the last keeper, Luigi Critelli. In his first months of service in 1994, while resting, he heard knocking and voices downstairs. Going down, he found no one, and no one confirmed having looked for him. Even today, the automated lighthouse keeps solitary watch over the cliff, keeper of secrets and a timeless panorama.
