Citadel of Bonifacio, Medieval citadel in Bonifacio, France.
The Citadel of Bonifacio is a medieval fortress built on limestone cliffs at the southern tip of Corsica, overlooking the narrow strait toward Sardinia. It consists of defensive walls, towers, a keep, and a dense network of lanes running between old stone houses.
The fortress was founded in the 9th century by a Ligurian lord to protect the settlement from attacks by sea. In the 13th century Genoa took control and significantly expanded the fortifications to secure its hold over the strait.
The old town streets follow a layout that still reflects the Genoese presence in Bonifacio. Small shops, stone houses, and churches stand close together, giving the district a character that feels different from other Corsican towns.
The site sits in the upper part of Bonifacio and is reached on foot through steep lanes. On hot days, coming early in the morning or late in the afternoon makes the walk more manageable, as shade is limited.
Beneath the fortress lies a cistern cut into the rock in the 15th century, designed to store drinking water for the whole population during long sieges. This space is still partly accessible today and offers a rare look at how a medieval fortified town managed its water supply.
