11 Extraordinary Cliffside Villages & Towns Clinging to Impossible Perches

4. Bonifacio, Corsica, France: The Limestone Citadel

Bonifacio, at the southern tip of Corsica, is a fortress town dramatically situated atop towering white limestone cliffs, sculpted by wind and waves. Its ancient citadel, with narrow medieval streets, seems to float above the turquoise waters of the Strait of Bonifacio. The King of Aragon's Stairway, a daring flight of 187 steps carved into the cliff face, legendarily built in a single night, exemplifies the town's audacious relationship with its perch. This natural harbor and strategic stronghold is a breathtaking fusion of geological wonder and centuries of history.
