The Minoan Kydonia was built at the current location of the old town of Chania. Kydonia was the third largest town of Minoan Crete. Here developed a thriving craft industry and the town became rich through sea trade, which was favored by its position. Indeed, the ancient writers mention Kydonia as the mother of the Cretan towns.
This fortress was originally built by the Byzantines on the acropolis of ancient Cydonia, on a hill next to the present medieval City of Chania. This point is still the highest in the region, as you look at the right when walking to the Venetian harbor.
