There’s not a lot left of this castle, but it’s got a nice playground around it and has a good information panel.

Very nice Welsh castle ruin set in a public park. Easy to get to and walk around but not a lot to see other than a few walls. Well done interpretive signage.

Worth a visit as you head into the beacons

Not much to see as most of the castle was destroyed but historic and peaceful nonetheless

Ruins of a castle built in the 13th century by Sir Grimbald Pauncefote to keep the Welsh subdued after claiming their lands.

It was originally a Norman motte and bailey fortification built of timber in the 12th century. You can climb the motte and look around at the incredible views as well as a second tower of the ruined castle. All that currently remains is a tower and partial gatehouse. Destroyed by Owain Glyndwr and his army.

The castle is located in a public park with a children’s playground. Close to the amenities that a town centre brings. Parking is a bit tricky but manageable.
