The monastery of St. George lies on the landmark hill of St. George, on the northern outskirts of the city of Kilkis. Apart from St. George, the church also facilitates the worship of St. Anargyroi and St. Dimitrios. From the initial buildings of the monastery only the katholikon (=main chapel), which was built in the 1830s, still stands today. It is a three-aisled wooden-roofed basilica with a peristyle on the west and south sides.
Its interior is decorated with frescoes, dating to the second half of the 19th century, while its colorful paneled ceiling is quite impressive. The icons of the temple are the works of renowned painters from Kolakia and date in 1835-1846. Equally important are also those icons brought by the refugees after the Asia Minor disaster of 1922. The oldest surviving relic of the monastery is an apostolikon of unknown origin, dated in the 17th c.
