The St. Mary’s Church in Rõuge was originally built in 1550, but it was damaged badly in the Great Northern War. The present church was reconstructed in 1730’s. In 1854 the church obtained its organ and the altar picture of 'Christ on the cross' by R. von Mühlen.
In 1860 the building was completely renovated, with the walls being made higher and a mirrored arch installed. The Kriisa brothers donated a 31-register organ they had built to the church in 1930. The first Estonian pastor in Rõuge was Rudolf Gottfried Kallas.
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.
