At the northern end of Lake Lampackie stands a castle built in 1788 for the then lord of the manor, Johann Sigismund von Oppeln-Bronikowski. This unfinished brick building was once the center of the Sorquitten estate. Between 1850 and 1856, under the lord of the manor, Julius von Mirbach, it was rebuilt in the neo-Gothic castle style of an English manor house. The castle walls have since been crowned with battlements. Next to the main building stands the so-called carriage house, a separate building.
The castle includes an English-style landscape park, whose form dates back to the 19th century. It is characterized by ancient oaks and several other protected tree species.
During the First World War, on August 26, 1914, the first day of the Battle of Tannenberg between the invading Samsonov Army and the German defenders, Russian soldiers spent the night in the castle. The castle caught fire and burned down on the night of August 27-28, 1914, along with all its valuable furnishings. In 1922/1923, it was rebuilt by the last German lord of the manor under the supervision of the Berlin architect Otto Rüger. The building survived the Second World War largely unscathed; only the interior furnishings were lost through looting in 1945.
After 1945, the castle was used as an administrative building and warehouse for the now Polish estate administration. In 1957, it became a convalescent home for the Warsaw Ursus machine factory. Today, the castle and park are once again privately owned; the castle houses the two-star Hotel Pałac Sorkwity. In June 2012, the castle appeared unoccupied, and there was no evidence of a hotel operation.
The idyllically situated castle in Sorquitten (Sorkwity) was built in 1788 for the then lairdowner, John Sigismund of Opole-Bronikowski. Several conversions followed until today.
