The first known owner of Ovesholm estate was Åke Holm in 1580. In 1620 Ove Urup built an earlier main building near to the current site. In 1774 it was donated to Henning Reinhold Wrangel and his son Carl Adam Wrangel af Adinal built the present castle between 1792-1804. Carl Adam also created a notable library and collection of art and sculptures to Ovesholm. The latest enlargement was made by Axel Hugo Raoul Hamilton in 1857. Today Ovesholm is still in Hamilton family's possession and not open to the public.
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.
