2500–2200 BC and was named by Colin Renfrew, after the fortified settlement of Kastri near Chalandriani on the Cycladic island of Syros.
There are numerous cultural connection between the settlement of Kastri on Syros, and Anatolia.
Kastri was a small town surrounded by a fortification system with horseshoe-shaped bastions, quite similar to the much bigger fortifications of the same time period at Liman Tepe, on Turkey's western coast near Izmir.
The depas vessels, the bell-shaped cups, and incised pyxides "are entirely Anatolian in character'.
Kynthos site), Naxos (Panormos fort) in the Cyclades, and Palamari on Skyros are quite similar settlements of the time, and they have also been linked with the ‘Anatolian Trade Network’.
