Halk church is a whitewashed church with a lead covered roof, which consists of a Romanesque choir and nave. Later, an expansion towards the west was added, as well as a sacristy, weaponhouse, chapel and an east facing tower, which is rarely seen.
The alter tablet is a beautiful combination of parts from a late-gothic alter tablet, which has been inserted into a late-renaissance frame from around 1640.
The church has an unusually large amount of fixtures from the Middle Ages, including beautiful sitting Mary with child from ca. 1275. There is also a crucifix from the same era, with side figures, where Mary is original, while John is from the 1400s. A canopy tablet with the crowned and blessing Christ dates from ca. 1400. A processional crucifix is from the first quarter of the 1500s.
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.
