The Church of Virgin Mary is a three-aisle basilica church (the nave is higher than the aisles) with large separated chancel closed by five-side apse. It was erected in the second half of the 14th century and enlarged in 1500s. The church was partially damaged during II World War and rebuilt in 1948. In 2003 the spire and dome of the church tower were reconstructed.
More valuable monuments in the temple are pulpit coming from late Renaissance made in 1609-1630 by master from Słupsk, Paweł Waltersdorf and funded by the guilt of amber-processors (with 43 members at that time). The pulpit is covered with bass-relieves, richly ornamented polychromed and gilded. The entrance to the pulpit is embraced by a portal (the lock in the door comes from 1609). Marvelous, first final of the pulpit, the so called amber crown from the first half of the 17th century was taken away during II World War. Worth attention are also hanging candelabra – some Baroque from the 18th century, some Neo-Rococo from the 19th century – as well as numerous Baroque candlesticks form the 17th-18th centuries and later from the 19th century.
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.
