Constructed circa 1864-70 by Sir Joseph Bazalgette. An extensive section of the Grade II listed granite retaining wall and parapet with piers and stairs was deconstructed, salvaged, adapted, and re-built as part of the Tideway Project.

Paye were initially employed under a PCSA to carry out survey and exploratory works to produce detailed dimensional drawings of the listed masonry that needed to be deconstructed to accommodate the change to the foreshore, connection of the Tideway Tunnel and construction of the new public realm.

The main works involved the careful deconstruction and salvage of listed granite walling and carved Lions Heads. Sections of salvaged granite were transported off site to be machined for re-use in raising the wall up negating the need for new masonry.

Due to the weight of the granite each section had to be craned off and on using the site crawler crane, the Lions Heads, the heaviest weighed 8 tonnes.
