Castell Henllys is an archaeological site near Nevern in north Pembrokeshire, Wales [1]. The Iron Age hillfort has been the subject of an ongoing excavation since the start of the 21st century [1]. Four roundhouses and a granary have been reconstructed on their original Iron Age foundations – some 2,000 years old – the hillfort being the only site in Britain where this has been done [1]. The Castell Henllys site includes significant earthworks and fortifications [1].
