Aci Castello

Aci Castello is a Norman-era castle built from local black lava stone on a rocky basalt outcrop jutting into the Ionian Sea north of Catania. The fortress was constructed over earlier fortifications and served as a strategic coastal defense point. Its dramatic volcanic-rock setting and commanding sea views make it one of the most distinctive castles in Sicily.
