The fortress Revellino del Porto on the northwest side of the port of Chania was constructed by Venetians to prevent any enemy danger for the port. Its construction began in 1610 and completed a few years before the fall of the city in Turks in 1645.
The interior was organized to barracks and ammunition storage areas. It was also the headquarters of the Army Commander of the city. In about the middle of the courtyard, there is a large domed water tank that gathered rain water from the roofs. On the northern side of the wall there are six arched openings that included cannons for the protection of the entrance of the harbour.
During the Turkish period Revellino was used as barrack (Firka = barrack), for that reason the name Firka is still used today. The arched openings were used as prisons from the Turkish period to the civil war. On the corner watch tower of the Fortress the Greek flag of the Unification of Crete was raised on December 1st 1913 in an official ceremony. Today, at the entrance of the Fortress is situated the Maritime Museum of Crete.
