History: The castle on top of the island was built by the Venetians to protect Crete from a Turkish occupation. It was one of the last unconquered bastions and it was the first area of Crete to be liberated from the Turks in 1825 (Turks were expelled from all the rest of Crete only by 1898). 3000 Cretan rebels were planning operations from Gramvousa.
During this period of turmoil, the residents of the island started looting boats passing through, which gained the island its pirate reputation.
