Gori Castle is a medieval citadel in Georgia, standing above the city of Gori on a rocky hill. The castle first appears in the 13th century records but archaeological evidence shows that the area had already been fortified in the last centuries BC. The fortress controlled major strategic and economic routes and accommodated a large garrison. In the 16th century the Ottomans captured it to overawe Tbilisi. In 1598 the Georgians besieged it to no avail; in 1599 they feigned a relaxation of the siege for Lent before launching a surprise attack at night to regain the citadel. The fortress continued to change hands between the Georgians and the Persians in the 17th century.
The citadel acquired the present-day form under the Georgian kings Rostom of Kartli in the 1630s and Erekle II in 1774. After the Russian annexation of Georgia in 1801, the fortress was garrisoned by a Russian grenadier battalion, but its importance gradually declined and the fortifications went defunct.
Gori Fortress was significantly damaged by the earthquake in 1920. The best preserved structure is Tskhra-kara ('the Nine-gated'), which looks to the west, and is adjoined by the supplementary walls on the south and east.
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.
