The Gate of Spalen (Spalentor) is a former city gate in the ancient city walls of Basel. One of the three remaining gateways, it is regarded as one of the most beautiful gates of Switzerland.
In October 1356, a major earthquake destroyed the old Basel. Then local people surrounded their newly built city with a high city wall and a moat in front of it. The ring wall had over 40 towers and seven of them were gate towers like the Spalentor (completed in 1473-74).
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.
