Koules (Rocca a Mare) Venetian Fortress

Koules, also called Rocca a Mare, is the Venetian sea fortress at the end of the breakwater that guards the old harbour of Heraklion in Crete, Greece. Built between 1523 and 1540 when the city was the Venetian capital Candia, it protected the port and its arsenals from Ottoman and pirate fleets. The square fortress has thick walls of dressed stone, and the Lion of St Mark, symbol of Venice, is carved on the seaward face. Inside, a ground floor of long vaulted halls, once used as storerooms and barracks, now hosts changing exhibitions, and stone stairways and ramps lead to the upper level and the roof terrace. From the terrace visitors look back across the harbour to the Venetian arsenals, the minarets and domes of the old town and, on clear days, towards Mount Juktas, while the open sea lies on the other side. The walk out along the breakwater is part of the experience, passing fishing boats and anglers, and is best made in the late afternoon when the light turns golden and the heat eases. A typical visit takes 45 minutes to an hour. The fortress is about ten minutes on foot from Lions Square and five minutes from the port. Summer hours are reported at about 08:00 to 20:00 and winter hours at about 08:30 to 15:30, with closure on Tuesday and last admission twenty minutes before closing; admission is listed at EUR 10 full and EUR 5 reduced, though sources vary. The terrace is exposed, so wind on the breakwater can be strong and shade is limited in summer. Crowds are heaviest around midday when cruise passengers arrive, while the final hours before closing are calmer and best for photographs of the harbour and the Lion of St Mark relief.
