The Pitareti monastery consists of the Theotokos church, a belfry, the ruined wall and several smaller accessory buildings. The main church appears to have been built in the reign of George IV early in the 13th century. Its design conforms to the contemporary canon of a Georgian domed church and shares a series of common features – such as a typical cross-in-square plan and a single lateral porch – with the monasteries of Betania, Kvatakhevi, and Timotesubani. The façades are decorated, accentuating the niches and dormers. The entire interior was once frescoed, but only significantly damaged fragments of those murals survive.
The monastery was a property and a burial ground of the noble family of Kachibadze-Baratashvili and, since 1536, of their offshoots – the princes Orbelishvili. A 14th-century inscription mentions a ctitor – the royal chamberlain Kavtar Kachibadze. Another inscription, from a grave stone, records the name of Qaplan Orbelishvili who refurnished the monastery in 1671. The monastery thrived at Pitareti until 1752 when it was forced to close due to a marauding attack from Dagestan.
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.
