The parish church dedicated to St .George is mentioned for first time in historical sources dating 1229; the earliest church on the site was a Late Romanesque Brick Gothic basilica built without a steeple. In 1289, the basilica was largely destroyed in a fire. Thanks to contributions from the sale of papal indulgences, St. George's church was rebuilt as a Gothic four tiered hall church with three naves; it was consecrated anew in 1307. Around 1400, the hall choir was enlarged and a large hall-style ambulatory was installed. This set of renovations also saw the installation of two-storied, transept-style annexes in the northern and southern parts of the church adorned with ornamental gables. In 1612, the steeple top caught on fire and was replaced by a humble gabled roof.
The church's interior houses many valuable works of art. Amongst the most notable dating to the pre-Reformation epoch are a two-tiered convertable winged alter (ca. 1421), an oak sculpture depicted Jesus as a man of sorrows (1400) and a group of crosses representing Christ's triumph (1480). Valuable images and carvings dating to the Rennaissance include the church's pulpit (1580) and the alderman's bank (1608-23); equally valuable are a baptism font from 1620, with their large brass basins dating to the 15th century and a Friese-3 brand organ (1871). Extensive renovations of the church's interior were carried out in 1844 and 1898; the latter aimed to render visible once more the medieval form of the church's Brick Gothic walls.
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.
