Ubisa (Georgian: უბისი) is a small village and a medieval monastic complex in Georgia, particularly in the region Imereti, some 25 km from the town Kharagauli.
The monastic complex of Ubisi comprises a 9th-century St. George’s Monastery founded by St. Gregory of Khandzta, a 4-floor tower (AD 1141), fragments of a 12th-century defensive wall and several other buildings and structures.
The monastery houses a unique cycle of murals from the late 14th century by the medieval Georgian painter mononymously known as Damiane.
The monastery is also known for its honey made by the monks.
