Introduction

Koules Fortress stands at the tip of the breakwater guarding Heraklion's old harbour in Crete, a sea fortress the Venetians built in the 16th century and called Rocca al Mare. Its massive stone walls and cannon batteries once defended Crete's maritime gateway; inside, restored halls evoke barracks, powder magazines and prisons. Climb to the ramparts for sweeping views over the busy harbour and city coastline — a three-dimensional textbook of Heraklion's Venetian and Ottoman past.
