Victorian stairs and causeway on the Thames foreshore at Shad Thames, next to (south east side of) Tower Bridge, London.
"Stairs already existed at that spot in 1684 when Greenville Collins produced a survey of the Thames from London Bridge east. The current stairs are much more recent with remains of a granite sett causeway" The City of London Archaeological Society.
