You are quite right, Jack. Turns out the hill was fortified by the Celtic Durotriges in around 500BC, the Romans came along around 46AD and within 30 years the tribe was fully Romanised...or so Wikipedia tells me. To walk the ditch and ramparts nowadays is still an experience in itself, we tried to imagine the struggle an invading force would have had storming the steep slope, then the rampart, the ditch, the counter rampart...and yet nowadays it is such a beautiful, serene spot. To think of all the earth-moving undertaken (by hand!) at the top of a steep hill some two and a half thousand years ago...staggering. Yester-century's battleground is now a beautiful haven for wildlife.Jack Harrison wrote: You have to hand it to the Romans, they showed amazing foresight re butterfly habo creation!!!
I think the fort pre-dates the Romans even though they might subsequently have made use of it.
I'm very much enjoying our Big Year attempt, already I'm seeing parts of Britain I'd never normally visit, some quite close to home. Plus new species too! Happy butterflying everybody!
