Visited 23rd March 2003: We visited Penmaen-Gwyn after spending an hour or so at Strata Florida Abbey just down the road. The stone stands on a small hill just north of the road (south of the forestry track, contrary to the impression given by Multimap).
There's a picnic place nearby, but also ample parking at the bottom of the forestry track. The boys were asleep when we arrived, but the stone is so close to the road that there was no problem leaving them in the car. The sunlight through the trees was beautiful, and we took the opportunity enjoy the place in a strange child-free quiet. Very pleasant.
Visited 23rd March 2003: This stone stands to the south of the mountain road between Tregaron and Beulah, and may not be prehistoric. The only reference I've yet found for it (Cambria Archaeology
) suggests it may be a post-Medieval milestone or standing stone. They list it without a name, so I've named it after the stream that runs nearby.
Having visited the stone, I'm not sure whether it's prehistoric or not. It looks to me like it's too far off from the road to be a milestone, but it could be a boundary marker (a small one at that though). Could it be a kerb stone from a cairn? Not the most awe inspiring site in itself, but enigmatic, and beautifully positioned.
Visited 23rd March 2003: We drove up to the farm and asked permission to go and see the standing stone. The farmer was fine with this, and asked us to park in the yard. Here we were met by a big friendly horse who thought he was about to get his dinner (William loved that).
The stone is very near the farm, but approaching from the farm it's difficult to spot until you're almost next to it. I found this site rather charming because the stone itself leans at an extreme angle, and is surounded by farmyard tat (a tractor tyre, an old gate and a water tank). The objects around the stone probably protect it from livestock.
We spent a while at the stone, and came away with a a good feeling about it. Well worth a visit if you're in the area, but only if you don't mind standing stones that are barely standing.
