Metekhi was one of the earliest inhabited areas on the Tbilisi's territory. According to traditional accounts, King Vakhtang I Gorgasali erected here a church and a fort which served also as a king’s residence; hence comes the name Metekhi which dates back to the 12th century and literally means “the area around the palace”. Tradition holds that it was also a site where the 5th-century martyr lady Saint Shushanik was buried. However, none of these structures have survived the Mongol invasion of 1235.
The extant Metekhi Church of Assumption, resting upon the top of the hill, was built by the Georgian king St Demetrius II circa 1278–1284 and is somewhat an unusual example of domed Georgian Orthodox church. It was later damaged and restored several times. King Rostom (r. 1633-1658) fortified the area around the church with a strong citadel garrisoned by some 3,000 soldiers. Under the Russian rule (established in 1801), the church lost its religious purpose and was used as a barracks (R. G. Suny, p. 93). The citadel was demolished in 1819 and replaced by a new building which functioned as the infamous jail down to the Soviet era, and was closed only in 1938.
The Metekhi church is a cross-cupola church. While this style was the most common throughout the Middle Ages, the Metekhi church is somewhat anachronistic with its three projecting apses in the east facade and the four freestanding pillars supporting the cupola within. The church is made of brick and dressed stone. The restoration of the 17th, 18th, and 19th centuries mostly employed brick. The facade is for the most part smooth, with decorative elements concentrated around the windows of the eastern apses. Horizontal bands below the gables run around all four sides and serve as a unifying element. The north portico of the main entrance is not a later addition but was built at the same time as the rest of the church.
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.
