History+
The origins of Broock date back to the 15th century, when the place, then also called Duvelsbrueke, was a knightly fief. Originally, a castle complex known as “Schlossberg” was located here, securing an important river crossing on the Tollense. Until 1652, the estate was owned by the noble Buggenhagen family. After their extinction in the male line, the estate changed hands. Around 1705, Christian von Linden, a Stettin wholesale merchant ennobled by the Swedish king, was enfeoffed with Broock. His grandson Christian Bogislaw von Linden, a Prussian major general, had a manor house built in the “Dutch style” around 1770. In 1785, the house and estate passed to a branch of the von Heyden family, who from then on called themselves Heyden-Linden. Between 1840 and 1850, under Hans von Seckendorff, who became owner in the first half of the 19th century, a renovation in the Neo-Gothic style was carried out according to designs by Friedrich August Stüler.
