Corsica’s most important port is nestled at the base of the northward-pointing finger of Cap Corse, between a looming mountain and the sea. The oldest part of town is dominated by the honey-colored Genoese citadel, which today holds the museum of history. The busy, 19th Century Place St-Nicolas is bordered in plane trees and pleasant cafes. There are a number of interesting churches, including the twin-steepled St. Jean-Batiste and the church of St.-Croix, which has a gilded ceiling and a curious black oak cross recovered from the sea in 1428. Climb the winding stairway from the waterfront to the Jardin Romieu for wonderful views over the town and the Vieux Port.
