Bubenstein Castle (Ruine Bubenstein), also called Neu-Falkenstein, is a ruined spur castle on the northern side of the Höllental valley, about 500 metres west of Old Falkenstein Castle above the village of Falkensteig in the municipality of Buchenbach in the southwest German state of Baden-Württemberg.
The castle was built by Walter of Falkenstein in the 13th century and in 1266 its residents were recorded as the lords of Falkenstein. In 1328 the lords of Staufen were named as its occupants. In the 19th century, part of the castle rock was blown up for the railway line and in 1960 the castle was dismantled due to its poor state of repair.
The bergfried of the castle measured 10 by 10 metres, and the neck ditch was 5 metres deep and 8 metres wide. Of the old castle only wall remains and the neck ditch survive.
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.
