The Skopje Aqueduct is the only aqueduct in Macedonia, and one of three largest and well preserved in the former Yugoslavia.
The question of when the Skopje Aqueduct was built is unclear. There are three theories, it may have been built during the reign of Rome (1st century), during the reign of Byzantine Empire (reign of Emperor Justinian I) or during the reign of Ottoman Empire. According to this latest theory the aqueduct was built in the 16th century for the many Turkish public hamams.
This aqueduct was in use until the eighteenth century. Only about 386 meters with 55 arches of this structure of stone and brick remain.
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.
