The Basilica St. Johann was erected by Stengel between 1754 and 1758. It has been painstakingly renovated and is now a perfect example of 18th century Baroque beauty: the pope even granted the church the title “Basilica Minor”. Not to be missed are the bronze portal and the entrance area, which were designed by the Saarbrücken artist Ernst Alt.
The church organ is particularly striking. It consists of three individual parts, the main organ and the two choir organs. They can by played individually or together. The St. Johann Basilica organ is hence composed of 60 sounding stops and a total of 4,312 pipes. This remarkable and multifaceted instrument is exceptional in both its construction and its tone spectrum and is renowned far beyond Saarbrücken and the Saarland.
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.
