The abandoned monastery of Panagia tou Sinti is situated on the banks of the Xeros River in Pentalia, and is dedicated to the Virgin Mary (Panagia) of Sinti.

The church has an octagonal dome with four windows and belongs to the first half of the 16th century. Its central nave is in good condition, and it is considered to be one of the most important buildings of the Venetian period.

The Monastery remained in operation until 1927 and thereafter was abandoned. In 1994, the Monastery of Kykkos undertook the maintenance of the Monastery, completing it in 1997 when it earned the Europa Nostra Award for the use of good restoration techniques and preservation of its original character.
