This historical castle made of limestone is connected to Ischia via a stone bridge across the water. It stands on a volcanic rocky islet and is one of the most recognisable and iconic sites in the Gulf of Naples.
The spot was used for defensive purposes for centuries, with the first recorded fortress built here in 474 BC by the Greeks. Since then, it has passed through many hands including the Normans, the Parthenopeans, the Romans and the Aragonese.
The islet itself has was once home to thousands of families, including an abbey of monks and a convent of nuns.
These days, the castle hosts regular art exhibitions and concerts as well as walking tours. You can also enjoy the views from one of its two scenic cafes.
Some of the top things to see within the attraction are a crumbling cathedral, the Nuns' Cemetery, and - if you're not too squeamish - a torture museum.
