Totally Thames: The Thames beyond London: Archaeology Downstream
National Maritime Museum, Ground floor, Lecture Theatre
Price: £8 (£6: Members)
CITiZAN community archaeologists Lara Band and Oliver Hutchinson reveal the forts, forests and fish traps of the Thames archaeological zone. These incredible sites become visible as the water recedes and the tides erode the river banks, the same action which puts them at risk.
