Šlokenbeka Castle is a fortified manor and the only existing example of a fortified manor centre in Latvia. The construction was started by the Livonian Order before 1544. It was built in a trapeze-type yard, which was enclosed with stone walls and portholes. In 1772 the attic roofs were added to the building.
In the 17th century towers with portals and weathervanes were erected, but Šlokenbeka lost its defence function, being then adapted for domestic purposes. At the end of the 18th century new buildings were built and old buildings were renewed. New gate towers were added at the north and south walls. Between 1841 and 1845, a new manor house in classicist style was built at the north wall. In the 1930s Šlokenbeka lost some of its buildings. During Soviet times it housed the 5th road maintenance unit. Now it contains the Latvian Road Construction History Museum and a restaurant.
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.
