The New River, London N5

It's not New and it's not a River; the New River is an artificial waterway built in 17th century to bring drinking water from Hertfordshire to Sadlers Wells in London. The total length is about 38 miles and the river still serves its original purpose, except that the final stretch, south of Stoke Newington reservoir, is no longer used and is mostly covered over. A signposted footpath now follows the route. Here the course of the river runs under Petherton Road, London N5.
