9Aragonese Castle, Ischia

Aragonese Castle overlooks the Gulf of Naples from the top of a volcanic rocky islet linked to Ischia Island. Dating back to 474BC, the castle went through a tumultuous history before being sold to a private owner in 1912.

Frescoes adorn the walls of ancient churches and crypts, and there’s also a torture museum, the former nunnery and abbey, as well as beautiful gardens. There’s a lift to get to the top and a restaurant that offers stunning views of the bay.
