The Roman aqueduct of Segovia was built, probably in the 1st century BC, to bring water from the mountains to the hilltop settlement of Segovia. It was a massive feat of engineering as it ran for around 15 km and had to cross a wide valley before it entered the city. It was used to bring water to the town until the 19th century.
Today the aquduct is part of a UNESCO World Heritage Site that also includes the old city and fortifications of Segovia. It is an enormous construction of masonry, 813 m in length, consisting of four straight segments and two superimposed arcades borne by 128 pillars. At the lowest point of the valley, the Aqueduct stands at a height of 28.5 m above ground. The tall arches of the aqueduct bridge are a major tourist attraction.
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.
