Architecture in Prčanj bears witness to its prosperity in the 17th and 18th centuries. The town's waterfront consists of a long line of stone villas, unified by their beautiful facades and separated by gardens and olive orchards.
The most impressive feat of architecture in Prčanj is the Birth of Our Lady church. It seems out of proportion to the number of inhabitants and took 120 years to build (1789–1909). It was designed by a Venetian architect Bernardino Maccaruzzi. The church has a monumental baroque facade with Corinthian and Doric columns and displays a collection of paintings and sculptures worthy of its size, including works by Piazzetta, Tiepolo, Balestra, Meštrović, and numerous other artists.
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.
