Sint-Petrus-en-Pauluskerk (Church of Saint Peter and Saint Paul) is built on the ashes of a previous church that occupied the site. King Leopold II enthusiastically supported a plan to build a new and more magnificent church. Construction started in 1899 and was completed and consecrated by Bishop Waffelaert on August 31, 1908. Its stained glass windows were destroyed during the two World Wars and were replaced by windows by Michiel Martens. The church is 70 meters long and 30 meters wide. Its spires are 72 meters high.
The church was built in the Neo-Gothic style according to plans by architect Louis Delacenserie, who based his design on the Gothic Cologne Cathedral and the Neo-Gothic Votivkirche in Vienna.
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.
