Ekebyholm is a castle-like mansion and a former manor located by Lake Syningen in Rimbo parish in Norrtälje Municipality in Stockholm county, Sweden. In 1932, the Adventist school purchased Ekebyholm. Presently Ekebyholmsskolan is located on site.
Ekebyholm in Rimbo (currently a part of Norrtälje) was attached with the estate of Mörby, owned by the Pomeranian-originated family of Slaveka. Bengt Gabrielson (Oxenstierna) af Mörby (d. 1591) acquired the estates of Mörby and Ekebyholm which were separated with Mörby passing to his elder son Gabriel Bengtsson Oxenstierna (1586-1656) and Ekebyholm passing to the youngest, posthumous son Bengt Bengtson Oxenstierna (1591-1643) who first had the manor built at Ekebyholm.
The current appearance was built by Arvid Horn during the 18th century.
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.
