Naxos Town or Hora is the island's port and capital. It is a lively town, of Cycladic architecture with a maze of narrow streets and tiny passages and makes an excellent resort. Behind the waterfront an extensive, almost Medieval Old Quarter stretches up the hillside where Kastro (Castle) is. Walking around and in the Castle is a must while the views will take your breath.

The old town up on the hill is divided into two neighborhoods, Bourgos where the the Greeks lived and Kastro (Castle), residence of the Venetian-Catholic nobility.

Places to visit include is the Archaeological Museum with Mycenaean pottery and Cycladic figurines, Portara (on Palatia islet) a huge portal (6 meters height, 3.5 meters width) of the unfinished Temple of Apollo (530 BC by Naxos' tyrant Ligdamis), the Venetian Kastro (Castle) where fortress walls are dated back to the 13th century. Inside the Castle is the Capuchins Monastery, the Catholic Cathedral, the Ursulines Monastery and the Catholic Episcopal Edifice.
