At first glance it looks like a very strange sculpture of a person in a rather odd position. However on closer inspection and peering over the greenery, it is a man on a bicycle.
A little research and I discovered it was a sculpture made to coincide with the 2007 Tour de France. The greenery around the sculpture has grown a lot in the past eight years. Where? On the roundabout at the entrance to the Rotherhithe Tunnel.
