The Basilica of St Michael was built between the end of 14th century and the 16th century. It is at the heart of the ancient quarter of Saint-Michel.
The pulpit represents Saint Michael slaying the dragon. The stained-glass windows were destroyed during the bombardment of 1940. The separate bell tower, which is 114 meters tall, was built in the 15th century. The tower can be visited every day from April to October.
From the late eighteenth century until 1979, over 60 of the mummified bodies were exhibited in the crypt. In 1881 a Gallo-Roman cemetery and catacombs were discovered under the tower, with several naturally mummified bodies. The mummies were found in 1791 according to other sources, in the adjacent parish graveyard which, having become full, was being cleared, with remains being transferred to catacombs; they further state that the bodies were removed to the cimetière de la Chartreuse in 1979.
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.
