Castell Henllys (Welsh for "castle of the old court") is an important archaeological site in north Pembrokeshire, Wales, on the A487 road between Newport and Cardigan, in the parish of Nevern.
It is about 20 minutes drive from where I live.
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.
Historic UK say:
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.
