Gramvoussa Fort is a 16th-century Venetian fortress situated on the rocky islet of Imeri Gramvousa off the northwestern coast of Crete. The structure was built between 1579 and 1584 to defend Crete against Ottoman expansion. It served as a strategic military outpost before being captured by Cretan insurgents during the Greek War of Independence in 1825. Following its capture, the fort became a base for revolutionaries who turned to piracy to sustain themselves, earning the island the nickname 'Island of Pirates.' The fort remains characterized by its substantial stone ramparts and cisterns designed to collect rainwater. It is accessible primarily via ferry services departing from the port of Kissamos. The site provides panoramic views of the Gramvousa peninsula and the Balos Lagoon.

Accessible only by boat; crossings are weather-dependent and typically operate from late spring through autumn.
