Naxos Old Town is divided into two neighbourhoods. Brougos where the Greeks lived and the fortified Venetian Castle (or Kastro in Greek) was built under the rule of Marco Sanoudo on the top of a natural hill where the Acropolis of ancient era was. Only two of the seven original seven twoers (those of Sanoudo and Glezos families) remain, although the North Gate survives and it is an excellent example of medieval fort entrance. The Venetian Catholic descendants still live in the old mansions which encircle the site.

Grotta is located at the North of the town and offers beautiful view to the sea, Portara, the sunset and easy access to the Old Town.
