No words can express my anger at the idiots that have damaged Bryn Cader Faner by erecting a stone in the middle.

This is awful. Is the stone taken from the outer ring?
Not sure where the stone has been taken from, but I understand that the issue has been reported to Cadw. It'll be interesting now to see how long it takes them to put rectify the situation and how exactly they go about it.
Looks like it's come from the centre rather than the ring, Moss spotted the stone in one of Postie's winter pics.
