Lierna Castle is built on a peninsula that protrudes into the lake Como and consists of a group of connected buildings, rather than a single building. The main portion of the current buildings was constructed in the 10th century in Romanesque style upon former Roman ruins. The castle includes the 11th-century church of Saints Maurice and Lazarus (Chiesa dei Santi Maurizio e Lazzaro), associated with the Order of Saints Maurice and Lazarus.
The last military use of the castle was in the mid-16th century by Gian Giacomo Medici, known as 'Medeghino' (the 'small Medici'), who was primarily a mercenary.
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.
