That is
Dartmoor, down south near Stonehenge they have funny ways down there
. The NY Moors have over a thousand burial mounds possibly thousands more. Outside of summer the cloud frequently comes down to ground level so you are walking in fog. We used to shelter behind the burial mounds, it is the only sort of shelter there is. As well as lots of bronze age and beaker people remains there are some of the earliest Christian sites in Europe outside of Italy. The region was part of the Kingdom of Northumbria which was comparatively rich and safe after the Roman empire collapsed. Despite all this you have no feeling of anything spooky or evil, more of a benign friendly presence, most people, including visitors say the same.
