Roughly following the line of the Greenwich Meridian, this east London Guided Walk incorporates modern art alongside the old industrial heritage. From the Bow Back Rivers at Pudding Mill Lane, we trace the industrial heritage of lower Lea Valley from fine porcelain in the 18th century through gasworks, gin, cosmetics and explosives to film studios. As we go, we follow part of The Line, London's first dedicated modern and contemporary art walk, finishing at the now green oasis of Gasworks Dock with the chance for refreshments before a short walk to Star Lane DLR station.
