The Agii Theodori Church in Servia used to be a catholic stavropegic monastery, glebe of the male monastery of Agii Theodori in Kastania. Out of all the buildings of the monastery, only one part of the enclosure and the rectangular water tank that was covered with a semi-cylindrical arch is now saved. The church dates back to the second half of the 11th century. More recent murals that date back to 1947 are saved, on the external and internal face of the western wall.
The church is single transept, with a semi-circular arch and ceramoplastic decoration. Its icons, characteristic of its type during the late and post byzantine period, in the wide area of Macedonia, are separated in three zones. In the upper zone, we see scenes of the Twelve Feasts and the Passions. In the middle zone we find Saints and Prophets on medals, while in the lower zone, we see whole body saints’ icons and the Deesis, on the northern wall. These murals that are works of two painters, belong to a group of similar works in Central and Western Macedonia. Its character is anti-classic and conservative, while they are connected to the so called Kastorian workshop, in respect to many iconographic details.
