Blije is known to have had a church ever since the early 13th century, which in catholic times was dedicated to St. Nicolaas. Of the original Romanesque church built in that century only the tower remains. The church itself was replaced by the current Gothic one in the 16th century. It's a rather big church for such a small village, a reminder of the time when Blije was a place of larger regional importance.
Various sources state that the church was built in c. 1540, but it is unknown what part of the church this date refers to; not only is there a small gap between the nave and the choir, the windows of the choir are narrower as well, giving reason to believe the choir was built first, perhaps when the old and shorter church was still standing. Probably in 1737 the roof of the nave was heightened with 3.50 metres, The tower was heightened shortly after, in c. 1741.

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.
