Rising proudly at the entrance of Heraklion’s Old Venetian Port, the Koule Fortress—also known as the Rocca al Mare—has stood watch over the harbor for centuries. Built by the Venetians in the early 16th century, this formidable structure was designed to protect the city and its vital maritime routes from pirate raids and enemy fleets. With its thick stone walls, battlements, and storied past, the fortress served not only as a military stronghold but also as a symbol of Venetian power in the Eastern Mediterranean. Today, its enduring presence tells the tale of Heraklion’s strategic importance and the turbulent history of Crete’s coastal defenses.
