Going with the flow

摘要

Emerging from the ground just to the west of Luton, the River Lea tracks a 68km journey through the wilds of Essex and east London, feeding finally into the Thames at Canning Town, opposite the Millennium Dome. It has represented an important boundary at least since Roman times, providing an edge to Danelaw, and more recently dividing the counties of Essex and Middlesex and the London boroughs of Newham and Tower Hamlets. Thanks to Abercrom-bie's 1944 London Regional Plan, the land that borders its final 26km is mostly parkland - the largest open space in London.
