This site is approximately 650m long and 40m wide; it is bounded by Cannon Street and Blackfriars Railway Bridges. There are four access points to the zone: three of these are of modern concrete, Globe, Bankside, Founders Arms Stairs. The fourth is underneath Southwark Bridge – the gate here is usually locked. The ground conditions on the site are generally firm (gravels) with considerable deposition at the top of the foreshore. Towards the downstream end of the site, the ground surface is particularly uneven due to modern rubble dumping.
