Today's state-sanctioned excercise pictures are from Warbstow Bury, a 2500 year old hill fort in north Cornwall. It's hard to take photos of because of the sheer scale of it but I thought I'd have a go. It's made up of two concentric rings of walls, each surrounded by ditches. The inner circle alone is about the size of a cricket stadium.
Here's one of the two 'entrances' to the inner ring:
The walls either side of this gap rise to over ten feet and the ditch outside them is almost as deep again. Here's the view out through that same entrance:
The high ground on the horizon there is Dartmoor, about 30 miles to the South East. Here's a close up:
Here you can see one of the inner walls, and the ditch outside it:
And here's the view from the top of the wall, with the ditch on the right:
It's the best place I know of to see Red Kites, but you'll have to take my word for it because there were none about today. It's also the best-preserved hill fort of this kind I've seen, and best of all hardly anyone else ever goes there.
