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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
