Cimetière Marin

The Gouvernail is a rock formation that on the map looks like the rudder of the boat-shaped Corsica. Follow the 168 steps down; there's a late 19th-century bunker dug into the rock for a cannon firing position.

From the SW edge of the citadel, 187 steps lead down the cliffs (their diagonal notch is very visible from the sea) to the Cave of St Barthelemy's Well. This cave, which nowadays can't be entered, has a pool of fresh(-ish) water percolated down from the limestone above, so it was an important water supply for the city. A well was also drilled down directly from near the church of St Barthelemy on the headland. The steps are named for Alfonso V, King of Aragon, who was awarded control of Bonifacio in 1421 by the Genoans but the city held out against him. Fanciful legend has his men fighting up the stairs and being beaten back, but more likely he simply tried to block the water supply to force the city's surrender. He was unsuccessful and left. Reserve on line to get your ticket.

St Dominique was built as a Dominican convent; all that remains is the church (listed above) and this Loggia, the former refectory. Its colonnaded square hosts a Farmers Market on Friday mornings.

A rare example of Gothic style in Corsica, this church dates from the 13th century. The bell-tower is of no known style: it starts square, turns octagonal, then tops out in battlements. Occasional concerts are held in the church.

The watchtower is the only citadel structure that remains from the original 9th-century Tuscan fortifications. It's been smashed down and rebuilt several times: the most recent destruction was in 1901 (as it gave enemy artillery too good a marker onto the town) and what you see now is a 1980 reconstruction.
