Marked as being roadside on Cerrigcochion road, Brecon. Couldn't find it, despite searching up & down. Must go back in the light!
26/4/06 - Found it! It's opposite Coleg Powys, just S of the traffic lights, at roadside. It's not a pillar, rather it's flush with the ground so almost hidden by grass.
