Castell Henllys, Iron Age fort in north Pembrokeshire, Wales.
Castell Henllys is an Iron Age fort on a promontory in north Pembrokeshire featuring four reconstructed roundhouses and a granary positioned on original archaeological foundations. The site spreads across about 30 acres of woodland and river meadows.
The fort was built about 2000 years ago by an influential family and housed a community of up to 100 people. Archaeological excavations revealed the precise layout of buildings and the way residents lived during that time.
The rebuilt structures show how Iron Age people organized their daily lives and used space. Walking through them reveals the practical ways residents managed work, shelter, and family routines.
The site is accessible on foot with marked paths through the woodland and information panels at each building. It is best visited in dry weather, as the pathways can become muddy after rain.
This is the only place in Britain where Iron Age buildings have been reconstructed directly on their original archaeological foundations. This hands-on approach helps visitors understand how ancient construction methods and designs actually worked.
