Castle of the Order of St. John in Łagów is located on a peninsula between the Łagowski and Ciesz Lakes. The first mention of the castle was under the name of castro Lagowe in 1299. The castle was built by the Order of St. John, and in later years fortificated in a trapezium-like shape. In the eighteenth century the residence was reconstructed into the Baroque architectural style. In 1812, after the secularisation of the Order of St. John, the castle went into private hands. Currently, the castle houses a hotel.
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.
