St. James Church dates from the seventeenth or eighteenth-century. Together with different tserkvas it is designated as part of the UNESCO World Heritage Site 'Wooden tserkvas of the Carpathian region in Poland and Ukraine'.
The tserkva in Powroźnik has existed since around 1600, but only a part of the former structure remains, arranged into the sacristy of the present tserkva. The architecture of the present tserkva was constructed between the seventeenth and eighteenth-century, with a major reconstruction in 1813. The tserkva was moved from its former location due to the danger posed by flooding, after which it was expanded. After Operation Vistula the tserkva was transformed to a Roman Catholic church.
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.
