Palace of Anna Vasa, a Swedish Princess, was built before 1564 at the Teutonic castle area by the Brodnica County starost Rafał Działyński, partly with the use of the Gothic walls. The palace was rebuilt and expanded as a residence by Anna Vasa of Sweden in the years 1605-1616 then it was the seat of successive starosts. Burned by Russians in 1945 and reconstructed in 1969. During its existence there resided starosts of prominent families. From the early 17th century Brodnica county was granted to members of the royal family. Besides Anna Vasa of Sweden the Brodnica starosts were: Constance wife of Polish King Sigismund III Vasa, his daughter Anna Catherine, wife of King Wladyslaw IV - Cecilia Renata, and his advisor and the Great Crown Chancellor Jerzy Tęczyn Ossoliński, Maria Kazimiera - wife of John III Sobieski, Crown Hetman Marcin Kalinowski and the Great crown Marshal Marshal Francis Balinski. Currently it houses a library and museum.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
