Retaining wall. 1850s. Squared limestone rubble wall with ashlar towers and dressings. Tall battered wall extends approx. 250m N from the North Yard Offices (qv) in three sections to the E of the Quadrangle (qv). Square stair tower to the S end with round-arched entrance in the tall plinth, open arched windows at the top and a granite string beneath a coped parapet. Steps out slightly with square tower, turns E at the N end to a further tower in the inner corner. A section of wall runs approx. 35m to the E with an arched walkway on the S side, to connect to a tower on the perimeter wall (qv). HISTORY: this imposing retaining wall was built for the cleared site of the Quadrangle. Reservoirs, now infilled, on the upper level pressured the hydraulic system serving the North Yard docks. It forms an impressive backdrop to the North Yard, continuing the line of the North Yard Offices (qv).
