Incredible place, as you would imagine, but very bleak. God/Jupiter only knows what the Romans must have thought about being despatched here. Luckily we were there on a good day, and could see for miles in all directions. The air was chock-full of the sound of skylarks, and much of the surrounding environment was marshy grassland, with the odd sheep farm (and pub) in between. It transformed into quite the terrifying landscape when it rained.
