Siesikai Castle is the residential castle built by Gabrielius Daumantas-Siesickis in the 16th century in the Renaissance style. His heirs were known as Daumantai, also called Siesicki, had given their family name to the nearby town. The masonry palace was reconstructed in the Neoclassical style after 1820 by Dominik Dowgiałło. Only 2 towers remain from the former castle, which had four of them in every corner of the palace. The castle has been undergoing restoration since 1990.
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.
