Ubisa is a small village and a medieval monastic complex in Georgia. It 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 made by Damiane apparently influenced by art from the Byzantine Palaiologan period (1261-1453).
The monastery is also known for its honey made by the monks.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
