St. Paraskevi Church in Radruż dates from the sixteenth-century, which together with different tserkvas is designated as part of the UNESCO Wooden tserkvas of the Carpathian region in Poland and Ukraine.
The tserkva belongs to the oldest and best kept wooden sacramental architecture tserkvas in Poland. Part of the prestigious World Monuments Fund (WMF) list of buildings worthy of preservation and financial sponsorship.
The tserkva is located on an oval hill, by the Radrużka stream, and together with the bell tower is surrounded by a wall (existent from 1825), with a fortification structure. The tserkva's structure is constructed out of a fir and oak framework. The tserkva was most likely funded by poseł to Sejm, and starosta Jan Płaza (died 1599). While being used for sacramental services, the tserkva was also used as a fortress against the invasions by the Tatars.
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.
