Network of green walks proposed along routes of London’s forgotten rivers

Charity urges mayor to back plans for signage and maps to guide walkers around lost waterways

There are clues to their existence in street names, in the winding of lanes and in the rushing sound of water deep in the capital's drains. For centuries London has been sculpted by its rivers. Today, though, while vestiges of some remain visible, most lie buried beneath pavements and submerged in the sewage system.

Now the Ramblers walking charity is calling for a network of new green walking routes tracing the paths of some of London's forgotten" waterways. It wants the mayor to back plans for signage and maps to guide walkers around these historic subterranean routes.
