Castell Pantglas is a sugarloaf shaped motte dating from 11th or 12th Century. It is built on
the site of a previous iron age settlement. There is speculation that the motte may have been built by the Lord
Rhys to protect the surrounding land which was known at the time as Cwmwd Widigada (Widigada Commote).
There is a permissive right of way to the site from the left hand side of Pantglas Farmyard.
Go past the lake and up the field to a stile in the far corner. Climb over the stile and into
the forest to the foot of the earthen castle defences.
Below and to the east of the castle you can see the site of an Iron Age fortress.
