Dekemastate country estate was built in the 14th century, at which time the house was a fortified dwelling. The first mention of the estate is from the year 1486. It was originally a rectangular stone house (called a stins in Frisian), and has been rebuilt since. Its owners include the Camstra family, the heiress of which married Hette van Dekema in the 16th century who gave the estate its current name. Other owners are Van Unia, Doys, Houth and Van Wageningen, the last of whom lived in the house until 1996. After that, the estate was taken over by the Dekema Foundation and went through extensive restoration. The inside of the house is filled with items from the past of its owners going back to the 16th century and features original furniture as well as a portrait collection. The house used to have two stories but was later redesigned and now possesses a spacious attic. The gardens around the manor feature canals, a moat surrounding the house, an herb garden and an orchard.
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.
