One of the A Coruña's most interesting monuments, San Anton castle (Castillo de San Antón) in A Coruña was constructed during the 16th and 17th centuries. A fortress built on a small island in the bay to defend the city against attacks coming from the sea, it effectively defended the entrance to the city against the English assault led by Francis Drake in 1589. There are some lovely collections of Celtic jewellery that were found on archaeological digs in Galicia on display inside the castle today.
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.
