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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
