A circuit of Ambresbury Banks in Epping Forest, an ancient earthwork built circa 500BC. According to local legend it was the site of the defeat and death of the great British Queen Boudicca at the hands of the Romans in AD61. The Iron Age banks and ditches formed an enclosure used as a cattle fold. Nowadays it is overgrown with beech trees and was covered with a carpet of leaves and beechmast when we visited. A series of lovely undulations striped by tree shadows in leaf filtered light.
