The main thoroughfare (Corso) was the present day Kanevaro street and went from the east gate to the west gate (Porta Colombo) of Kastelli. Along this street were the beautiful Venetian mansions of the noblemen, Permarin, Da Molin, and Zangaroli. The air raids at the beginning of the Battle of Crete in the Second World War destroyed them all. The portals from the Zangaroli mansion are in the Archaeological Museum's garden.

In the Kastelli (Platia Ekaterini) there is an excavation by a Greek and Swedish group of archaeologists that found, among other things, the Masters Impression, a clay seal. The picture shows a male figure on a wall with a large size city behind it. It is dated about 1450 B.C. and it is on display in the Archaeological Museum of Chania. Substantial remains of a Minoan city, which some archaeologists believe was the ancient city of Kydonia, were found here.
