The island has two significant settlements, the village of Messaria or Kythnos (pop. 561 in 2011 census), known locally as Chora, and the village of Dryopis or Dryopida Dryopida (pop. 325), also known as Chorio. Both villages are notable for their winding and often stepped streets, too narrow for vehicular traffic. The villages are very picturesque but in different architectural styles. Chora has the more-typical flat roofs of the Cyclades, while Dryopida’s rooftops are slanted and tiled. Chora is also notable for its large Greek Orthodox Church..

 

There is also a growing coastal settlement called Kanala on the east side of the island, and many of the larger beaches are settled by a handful of residents. Aghios Dimitrios, at the southern tip of the island, is a mostly modern settlement, with small vacation houses dotting the hillside above a wide beach that is dotted with sea daffodils. On the northeast end of the island lies Loutra (pop. 81), a village famous for its thermal springs, which are said to have curative properties. Although the large tourist hotel there has been closed for several years, the bathhouse is still functioning and visitors may soak in its marble tubs for a modest fee.
