How are you doing ?
I visited this island weeks ago during my trip to Greece, that was a really creepy place. The Venetians started to use it in 1526. Look at its history here :

We were there on the day time but it must be so creepy at night and maybe we can experience some haunting, especially during the night, gosh I would love to go back at night
Take care.
