One of a series following the Thames from London looking at industrial, maritime and military history, this walk takes in an area that was once dominated by the testing grounds of the Royal Woolwich Arsenal. We'll walk along canals that were once used for carrying gunpowder, see the site of storage facilities for cordite, land where tanks were tested and a stretch of water once used for testing torpedoes. This stretch of the Thames features a dangerous bend called Tripcock Ness – we’ll go past a lighthouse which still marks the area, and hear tales from the river. In the 1960s, the area was built on to create a New Town within the boundaries of London - Thamesmead. We’ll look at the idealism of the plan and how Thamesmead is developing today. The walk also visits Medieval Lesnes Abbey, before finishing at Abbey Wood station.
