Lonely Planet review
The citadel (often referred to as Haute Ville , upper town) is the main town centre. Set on the cliff-top promontory 70m above the harbour, the northern side overlooks Bonifacio Sound, while the southern ramparts give you dreamy views of Sardinia. On all sides, white limestone cliffs drop vertically and dramatically into the sea.
Within the clifftop citadel is a charming maze of alleyways with a distinct mediaeval feel.
