Walk around this once impregnable fortress by lantern light discovering 1,500 years of history.
In the 5th century the castle was a safe haven for more than 2000 Ischian families fleeing pirates, it became a residence for 12th century Norman noblemen, reaching its greatest splendour in 15th century under Alfonso of Aragon. He began a renaissance, attracting brilliant minds to share art and ideas, even Michelangelo came.
By this time there were 13 churches and a convent for the Poor Clare Nuns, which they built with their own hands as it was forbidden for men to assist them. Today you can visit a grim crypt with empty stone seats where deceased nuns were placed to decompose. Living nuns prayed around them, contemplating the temporal nature of life, and collecting their dissolved remains and bones.
