Keros is right opposite Pano and Kato Koufonissi, the most beautiful part of the view.
It has great archaeological interest and nowadays it is a protected archaeological site.
In antiquity it was called Keria according to a reference to the island on an inscription bearing the names of the tax-paying allies of the Athenian Democracy.
The island has an area of 15,042 square kilometers with a coastline of 27 kilometers.
In the soil there is white marble.
Archaeological finds from the Cycladic and early Cycladic civilization, such as the flute player and the harp player, as well as a host of others render Keros a significant archaeological site. Many of these finds are exhibited in the museum on Naxos.
On moonlit nights on gazing at the outline of Keros, you will distinguish the outline of a pregnant woman and the bust of a man lying head to head.
Keros has been uninhabited since the 1970s
