The Dominican Monastery in Ústí nad Labem was founded in 1186. The church was remodelled in Baroque style in 1718-1722 during extensive reconstruction designed by Litoměřice architect Octavio Broggio. At the wish of the Prior of Ústí, he based his design of the St Adalbert Church on the model of the Prague Church of St Ursula. Under the communist regime it was used for storage and later on, whitewashed and stripped of all furnishings, converted into an exhibition hall. The wall paintings from 1928 were probably by Albin Müller. The original monastery was a single-wing structure at first (in 1617-1650), its enlargement being impossible for financial and political reasons, the second wing was added during the Baroque reconstruction. The south wall of the church and monastery merges with the city walls.
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.
