On the northwestern side of the Venetian harbor stands Firkas Fortress, built by the Venetians in 1610 as Revellino del Porto, with the purpose of defending the entrance to the harbor. A few years before the fall of Chania to the Ottomans in 1645, the fortification was completed, becoming one of the city’s most important strategic points.

Inside, it housed barracks, ammunition depots, and the headquarters of the city’s military commander. At the center of the courtyard is the characteristic vaulted cistern that collected rainwater, essential for the garrison’s survival. On the northern side, six impressive vaulted gun platforms remain, designed so that their fire could fully cover the harbor entrance.

Firkas Fortress remains today one of Chania’s most emblematic monuments, recalling the city’s defensive past.
