The Monastery of the Virgin Mary of Mavriotissa is a monastery that is built on the spot where troops of Byzantine military commander George Palaiologos encircled the attacking Normans in 1083. It is believed that the emperor Alexios I Komnenos, built the monastery there to commemorate the event.
The monastery was initially named Mesonisiotissa ("in the middle of the island") and in the beginning of the 17th century it renamed itself to Krepenitissa ("of Krepeni") after the name of the nearby village Krepeni. Sometime from the middle to late 17th century it changed its name to Mavriotissa ("of Mavrovo") after the Greek village Mavrovo near Kastoria.
The monastery was a significant land owner in the village of Krepeni.
