Freundsberg castle in Tyrol was constructed in 1150 by the lords of Freundsberg. Originally the castle consisted out of a single keep, which is still intact up to this date. The chapel next to it was built afterwards in the year 1117. In 1467 the castle was sold to Archduke Sigismund of Austria, who rebuilt the castle and called it Sigismundruh for the duration of his reign.
From 1634–37 on, the castle was remodified as a 'castle church' or Schlosskirche. After passing to several other owners from 1812 on, Castle Freundsberg became a property of the municipality of Schwaz. They restored the castle from 1966 onwards.
Since 1948 is the castle a museum where the history of the city Schwaz and the silver mining industry in this region is documented.
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.
