The Welsh Crannog Centre, Llangorse
Crannogs are a type of ancient lake dwelling found throughout Scotland and Ireland; they were built out in the water as defensive homesteads from 5000 years ago. The Crannog on Llangorse Lake is the only Crannog to be found in Wales or England. It is situated in the waters of Llangorse Lake, which is the largest natural lake in south Wales. The Crannog was constructed in 916ad, probably by the King of Brycheiniog.
