This monastery, located on the slopes of Boztepe in a location overlooking the city, was founded between 1349 and 1390 during the reign of Alexios III. Girls' Monastery was built on two terraces and surrounded by a high protection wall. The Girls' Monastery, which was repaired several times, took its final shape in the 19th century. The first hall of the monastery consists of the rock church with holy water in the south, the chapel at its entrance and a few cells. Inside the rock church, there are inscriptions and portraits of Alexios III's wife Theodora and his mother Eirene.
