Jutting out above the Tavignano and Restonica Rivers, and the cobbled alleyways of the Haute Ville , the citadel’s oldest part is the château – known as the Nid d’Aigle, meaning ‘Eagle’s Nest’ – built in 1419. The 19th-century barracks now house the tourist office and the Museu di a Corsica , a must-see for Corsica culture buffs with its outstanding exhibition on Corsican traditions, crafts, agriculture and anthropology. It’s a joint admission for the museum and citadel.
If you’re not fussed about culture but would like to enjoy free views of the city and surrounding valleys, head to the belvédère (viewing platform), reached via a steep staircase just outside the citadel’s ramparts (it’s signposted).
