The fortifications of Chania are some of the most impressive sights in Crete and defensive structures in Greece. The city's walls date back to the Byzantine era, when they were first built on the acropolis of ancient Cydonia. The Venetians, who conquered Crete in the 13th century, made use of the existing fortress and adapted it to their needs. Today, the fortress is still the highest point in the city, offering stunning views. The fort was originally connected to the town by three gates, but only one of these - the eastern gate - remains today, even if ruined, as the west gate was demolished in 1928, and the third gate led to the down town area. Despite its age, the fortress remains an imposing presence in Chania and is a favourite destination among tourists.
