is one of the most spectacular ancient forts in Scotland. Two stone walls,
6m and 12m wide, enclose a large area (150m x 60m) covered with heather,
where there are a rock-cut cistern and a more recent rectangular turf structure.
Between the inner walls and the outer earthen defences, on the western slope
of the fort, there is a broken, now restored, boulder covered with at least
70 cupmarks. The name 'White' refers to the massive stone ramparts of the
fort. At the other side of the valley there is a twin, although earlier,
hillfort called Brown Caterthun.
