Saint Michael's Church was built in a late Gothic style. Documents from 1105 testify to the existence on the site of a chapel dedicated to St. Michael which was subordinate to another parish. The building was twice destroyed by fire early in the 12th century and rebuilt. From 1147 it was recognized as an independent parochial church.
Construction of the current late Gothic church was probably commenced in 1440, and took place in two phases, separated by a long interval. During the first phase, in the fifteenth and sixteenth centuries, the western part of the building was built, including the tower, the three-aisled nave and transept. This was completed in 1528. The construction of the western tower continued and by 1566 two levels of the tower were completed. Then, due to religious conflicts, not only did construction stop, but looting and destruction took place. Part of the church was destroyed in 1578 by Calvinists and in 1579 the old choir was demolished.
Reconstruction of the church only started in 1623. The early Gothic choir was replaced by a choir in Brabantine Gothic. Local architect Lieven Cruyl made a design for the unfinished western tower in 1662. The design provided for a spire of 134-metre-high in Brabantine Gothic style but was not implemented. As a result of these delays and cost concerns, the tower was in the end never completed. Only in 1828 was a flat roof built over the unfinished tower.
The sacristy in the north-east was constructed in Baroque style in 1650-1651.
The exterior of the sober late Gothic church is entirely constructed with sandstone from Brussels and Ledian sandstone. The church has a rich Neo-Gothic interior, including an altar and a pulpit in that style. There are various 18th century statues, including a Saint Livinus by Laurent Delvaux, a wooden St. Sebastian by J. Franciscus Allaert, eight marble statues of saints and a copy of Michelangelo's Madonna of Bruges by Rombaut Pauwels.
The church contains many Baroque paintings, including Christ Dying on the Cross by Anthony van Dyck, the Resurrection of Lazarus by Otto Venius and paintings by Gaspar de Crayer, Philippe de Champaigne, Karel van Mander, Jan Boeckhorst, Antoine van den Heuvel, Theodoor van Thulden and others.
There are confessionals from various style periods including a Baroque confessional from the early 17th century by François Cruyt with statues sculpted by Michiel van der Voort.
There are numerous silver and gold artifacts in the silver collection. An important item is the relic of St Dorothea, in silver. Very famous is the relic of the sacred 'Doorn' brought to the church by Mary, Queen of Scots, and a relic of the true Cross a gift of the Archduke Albrecht to Isabella in 1619.
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.
