Located to the north of Ano Mera, this 18th century nunnery is a typical
example of the monastic architecture of the Cyclades. It takes its name
from “Paleokastro”, the neighboring hill, crowned with a medieval
castle (early Byzantine, occupied until the time of Gizi), which has its
foundations on the remains of an ancient fortress.
This area is known as one of the two major settlements of the island in
ancient time. One can see here, among other things, the old church of
Agios Vlassis with its neighboring large dovecote and a prehistoric
grave-marker consisting of a single 3-meter-high granite slab.
