Ekebyholm Castle

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.

History
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.
