In 1763 Russian Empress Catherine II ordered to fortify Tartu again. It was decided to build a gunpowder magazine (Püssirohukelder) in the former city moat. The responsibility of the building was assigned to Field-Marshal General de Villebois. His engineers started to build magazine in 1768. The bricks are brought from the old Mary Church (about where the University Main Building is now) and the ruins of the bishop settlement on Toome Hill demolished in 1708. The magazine completed in 1778.
Today Püssirohukelder offers Estonian and German dishes and has room for up to 300 people.

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.
