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 city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
