The Hermannsdenkmal ('Hermann Monument') stands on the densely forested Grotenburg, a hill in the Teutoburg Forest range. The monument commemorates the Cherusci war chief Arminius (in German Hermann) and the Battle of the Teutoburg Forest in which the Germanic warriors under Arminius defeated three Roman legions under Varus in 9 AD. At the time it was built, the location of the statue was believed to have been very near the actual site of the battle, though it is now considered to be more likely that the battle actually took place near Kalkriese, a considerable distance to north west of the monument.
Earthworks of the monument began in July 1838, and the foundation stone was laid in October 1838. Problems emerged due the criticism for design and the financial viability of the project came to be questioned. It was inaugurated not before 1875, in the presence of Emperor William I and the crown prince, Frederick.
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.
