The stone is easy to spot being on the main road out of Peebles. Parking is also easy.
It is nice that this stone has been respected and cared for all these years. It says something that there was no sign of any graffiti or litter spoiling the stone. I would put the stone at approximately 1metre round.
Well worth looking out for when visiting Peebles – which is a very nice town. (and has an Historic Scotland site – that’s another one off the list!) :)
Looks a bit similar to market stone up in Ardgay
