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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
