The Walls is an Iron Age hill fort, a prehistoric village. It lies on the edge of Chesterton, near Worfield.
Its hard to see the size of the earthen bank that surrounds the Walls. Someone in Victorian times thought it would make the bank look more impressive to plant trees all along the tops.
The field, this year used for a cereal crop with poppies growing all around the perimeter, gives an idea of the scale of the fort.
