The wooden church in Ruska Bystra was built by worshippers in the first half of 18th century, in approximately 1720-1730. As it is considered to be the result of folk sacral civil engineering, there is no knowledge of an exact date of its origin or the name of the master builder or the master carpenter. During the canonical visit of Bishop Michael Emanuel Olsavsky from Mukacevo on 25th June 1750, the church was mentioned as 'in a good condition'.
The church is part of the UNESCO World Heritage Site of Wooden Churches of the Slovak part of the Carpathian Mountain Area.
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.
