Nekresi village was established by king Pharnajom (around 2nd-1st centuries BC). In the 4th century AD, king Thrdat built a church in this place. This church became a refuge to one of the Assyrian fathers, Abibus, in the late 6th century. Around this time Diocese of Nekresi was established, which existed until the 19th century.
The small basilica from the second half of the IV century is one of the earliest of the churches in Georgia. The church was recently restored, stone masonry repaired, roof rebuilt, windows put in place.
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.
