Looking south from an earthwork art sculpture of concentric rings by landscape artist Richard Harris at Theydon Bois Woodland Trust 222 acre wood on Abridge Road, Theydon Bois, Essex, England. The earthwork is directly at the west side of the M11 motorway, south of its junction with the M25. Between the raised chalk walkways will be planted British native trees. On the centre skyline is the City of London and the The Shard building.
