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:Střekov Castle (Schreckenstein) is perched atop a cliff above the River Elbe, near the city of Ústí nad Labem. It was built in 1316 for John of Luxembourg, the father of the Holy Roman Emperor Charles IV, to guard an important trade route to Germany. After changing hands several times, the castle was acquired by the Lobkowicz family in 1563. Its strategic importance led to occupations by Imperial Habsburg, Saxon, and Swedish forces during the Thirty Years' War, as well as successive sieges by Austrian and Prussian armies during the Seven Years' War.
Although Střekov Castle was heavily damaged during those conflicts and abandoned as a military installation by the end of the 18th century, the 1800s saw many poets and artists visiting the castle, drawn by a new trend of interest in romantic ruins.
