The parish church dedicated to St. Dorothy was probably erected by the end of the 15th century. In the end of the 16th century a bell tower was added to the nave. It was renovated and partially transformed at the beginning of the 19th and 20th centuries. The interior is decorated with a renaissance polychrome from the mid 16th century and with a mannerist one form the mid-17th century. The chapel is among the oldest of the corner joining wooden churches.

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.
