Koules (Venetian Fortress)

Rising proudly at the entrance to Heraklion’s bustling port, Koules Fortress, also known as Rocca a Mare, is a timeless sentinel of the city’s Venetian past. Built in the 16th century, this imposing structure once protected Crete from invaders and now invites visitors to wander its restored halls and terraces. Offering sweeping views of the sparkling Aegean Sea, Koules is more than just a fortress—it’s a journey into Heraklion’s storied maritime history.
