Playing ‘spot the prehistoric monument’ upon Pen Twyn Glas..... nearest to hand is an excavated Bronze Age cairn upon the foreground ridge sweeping to the right. Mynydd Troed, with associated chambered cairn, dominates the image (centre skyline) with Mynydd Llangorse and its hillforts/standing stone to its left. Castell Dinas is extreme right, with the Ty Isaf chambered cairn upon the valley floor somewhat nearer the camera.
