Nevern Castle, Pembrokeshire, was burned down in 1196. Most of the stones were subsequently re-used in local buildings. There are therefore few remaining stones.
This one was found in archaeological digs 2008-2018 led by Dr Chris Caple of Durham University.
It appears to have been part of the decoration of the Great Hall of the castle. The style is found throughout the Norman world of the 12th century. It suggests the Great Hall was impressively decorated, indicating the importance of the castle.
While most of the walls were constructed from local slate/mudstone, decorative features used stone that could be carved. This is a gritstone, probably brought from the nearby Preseli hills; there are also examples at St Dogmaels Abbey.
