We had seen this marked on the OS maps and it looked big. It is. An iron age fortification, it was a place of importance by the time of the Roman invasion in 43AD. It is thought to be the stronghold of Queen Cartimandua of the Brigantes.
Four miles of banks enclose an area of around 750 acres. The banks were originally 16' high and had a deep ditch round the outside.
There is a small sign on the side of the minor road between Forcett and Carlton. A gate and steep steps lead to the top of the rampart. A footpath used by dog walkers and horse riders runs along the top of the rampart through the trees. The ditch can be seen on the north side. The line of the rampart is marked by a row of trees until it eventually rejoins the road. Looking across the farmland, the line of the rampart can still be traced across the landscape.
There isn't a lot to see – just a bank of earth and a ditch, hence the rather low star rating. But you can't fail to be impressed by the size of the foftification.
