Fortezza of Rethymno

The Fortezza of Rethymno, a Venetian fortress on a hill that was possibly once an island, dominates the town and the western coast of Crete. The site may have held the ancient acropolis of Rithymna, with temples to Apollo and Artemis, though this remains unproven. A Byzantine settlement, the Castrum Rethemi, later occupied the area, but nothing of its walls survives. After a devastating 1571 raid by the Turkish corsair Ulu Ali Reis, who easily breached the town's token defences, the Venetians resolved to build a proper stronghold. Work began on 13 September 1573 under Governor Alvise Lando, using plans by Sforza Pallavicini, and was completed by 1580, with over 107,000 Cretans conscripted for labour. The bastioned fortress was never truly secure, lacking a ditch and buttresses. The Ottomans took it in 1646 and converted the cathedral of San Niccolò into the Mosque of Sultan Ibrahim Han. Today the outer walls survive intact, while restoration continues within.
