Castell Henllys (Welsh, 'castle of the old court') is an important archaeological site in north Pembrokeshire. The Iron Age hillfort has been the subject of an ongoing excavation for more than twenty years, accompanied by an exercise in reconstruction archaeology whereby experiments in prehistoric farming have been practised. Four roundhouses and a granary have been reconstructed on their original Iron Age foundations, some 2,000 years old, the only site in Britain where this has been done.
To the north of the site, where the entrance was, there are significant earthworks in the shape of several ditches and banks. Inside these fortifications, archaeologists have found evidence for numerous Iron Age roundhouses dating to between 500 and 100BC. Adjacent to the fort they discovered a farmstead settlement, which is believed to have been occupied throughout the Romano- British period.
During the summer the site provides training for young archaeologists and is a popular visitor attraction. It is owned by Pembrokeshire Coast National Park.
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.
