Enroute to Newcastle on Monday I just had to detour via the Terris Novalis which I've been drooling over since August.
Despite having a 15 year old map (oops ) we just about managed to find it. They are as impressive as I'd hoped, although they don't really fit being just across the road from a modern housing estate.
They are beautiful.
Not 100% precision tools, and the animal feet are unusual, but so wonderful to gaze at. We had a stroll around them then a climb on the level (the theodolite looked a bit too tricky to climb in heels).
