Iron Age Hill Fort.

Just on the next rise and a hair higher than Dolbadarn Castle was a grouping of rocks stuck into the ground in a way that wasn't quite natural. There was nothing but the sound of the wind up here. After relaxing for a while in the tall grass, an older gentlemen arrived with his Jack Russell. It turns out he comes there all the time to unwind and contemplate life. I asked him about the rock and he shared the history that this was a very old lookout post (pointing out the excellent views up/down the valley and the steep grade all around). The dog must have been old as it sat still most of the time.
