This is a pretty big stone – 14 ft tall – but it only seems to be on the old Ordnance maps? Chris Barber’s 1986 book ‘More mysterious Wales’ has a photo, so surely it can’t have disappeared?
You may have been to Devil’s Bridge? Well the devil was collecting stone for this over on the top of Trichrug Mountain. He’d bit off a bit more than he could chew with this huge stone, so sat down for a bit of a rest. He’d been gripping it so hard that his fingers left marks in the stone (can you see them?). He was just drifting off into a nice nap when a cockerel patrolling the field spotted him, and sneaking up behind gave a deafening crow. The devil leapt to his feet in surprise and ran off, leaving the stone behind. Where you’ll (hopefully) find it today.
Llech Bron means ‘huge brown stone?‘
