The Capital Ring is a strategic walking route promoted by London's 33 local councils, led by the City of London Corporation in partnership with the Greater London Authority and its functional body for regional transport, Transport for London, through which much of the funding is provided. It is called a "ring" because the route completely encircles inner and central London. The official start of the route is the Woolwich foot tunnel, but the nature of the route means that it can be started or finished at any point. The route signs feature a logo showing Big Ben in a ring of arrows.
