Warehouses 1 and 2, West India Docks North Quay (now West India Quay), Wapping, London: one of the two staircases in Warehouse 2

NOTES: These incombustible circulation routes were carefully separated from the storage areas. Built between 1799 and 1806, the West India Docks were the first of London's great enclosed docks. These two warehouses are all that remain of the row of nine warehouses designed by the Gwilts, later extended upwards in 1827 by Sir John Rennie.
