Rocca a Mare Fortress: Guardian of Heraklion

The Rocca a Mare Fortress, or Koules, stands as a proud sentinel at the entrance to Heraklion's Venetian harbor, a testament to centuries of maritime history and strategic importance. Originally built by the Venetians in the early 16th century, the fortress was designed to protect the city from naval threats and served as a crucial part of the city's defenses.Constructed on the site of an earlier Byzantine tower, the fortress we see today took shape between 1523 and 1540. The Venetians ingeniously used old ships filled with stones to create embankments, expanding the fort's footprint. The fortress has massive, two-story structure that covers an area of 3,600 square meters, with outer walls reaching up to 8.7 meters thick.Inside, visitors can explore 26 rooms on the ground floor, which once served as storerooms for food and munitions, meeting halls, and even prison cells. The upper floor houses a large courtyard, surrounded by crenellations, and once contained barracks, officers' quarters, a bakery, a mill, and a small church.Over the centuries, the fortress has undergone repairs and modifications, including additions by the Ottomans, who added battlements, gun ports, and a small mosque. Today, the Rocca a Mare Fortress is a restored landmark that welcomes thousands of visitors each year. It hosts cultural events and exhibitions, including findings from Jacques-Yves Cousteau's underwater expedition to Dia Island. Visitors can also see three Minoan shipwrecks and learn about the history of the fort and Heraklion. A visit offers a glimpse into the island's past and provides stunning views of the city and the sea.
