The church of St. George was part of the Bernardine Monastery. The first wooden church was built in 1468. It was replaced by the current brick church in the late 15th century and completed before 1503. It’s been ruined by fire three times, suffered the wrath of the Moscow army during the war of 1656-1659 and then had a bit of a rest during the 18th century before Napoleon turned it into a warehouse.
During Soviet times, the church was used to store medicine. It was returned to the Friars in 1993 in a pretty shabby condition, and restoration of its outstanding if run-down Gothic, Renaissance and Baroque interior has been slow to say the least. Ongoing restoration work has seen the addition of a new roof although the church itself remains locked for the foreseeable future.
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.
