|Built for||Built speculatively by John Kelk and John Aird & Co.|
|Architect||Sir John Fowler|
The scheme was developed speculatively by a partnership of John Kelk and John Aird & Co. The engineer responsible for designing the scheme was Sir John Fowler. The construction was undertaken by Kelk and Aird and the dock was officially opened in March 1868. After a slow start to the business and financial difficulties, Kelt and Aird surrendered control of the company to lawyers acting for the investors in December 1868. In recognition of its settled status the business was renamed the Millwall Dock Company in 1870.
The dock was used mainly for timber and grain, a trade which eventually moved down river to the Port of Tilbury with the construction of a major grain terminal in the 1960s. A McDougall's flour mill, the Wheatsheaf Mill (constructed in 1869), stood on the south side of the Outer Dock, but was demolished in about 1980. Nearby Sir John McDougall Gardens is named after one of the McDougall brothers, John McDougall, who was also a prominent local politician in Poplar.
From the 1960s onwards, the Millwall Dock experienced a steady decline – as did all of London's other docks – as the shipping industry adopted containerisation, which effectively moved traffic downstream to Tilbury. It finally closed to commercial traffic along with the other Royal Docks in 1981.
The West Ferry Printing Works, the largest newspaper print works in Western Europe, was built on the north side of Outer Dock between 1984 and 1986.
The Docklands Sailing and Watersports Centre, located at the far West end of the dock where the dock previously connected to the Thames, was established by the London Docklands Development Corporation and the Sports Council at a cost of £1.2 million in 1989.
While much of the area has been occupied by commercial office towers, Millwall Dock is also an area where several housing developments and apartment towers have been developed. During the 1980s the Clippers Quay housing estate was built around the old dry dock while the Mill Quay housing development was built on the site of the old Wheatsheaf Mill.
The dock is L-shaped, with an 'Outer Dock' running east–west, and an 'Inner Dock' running north from the eastern end. It originally contained around 36 acres (14 hectares) of water and had a 200-acre (81 hectare) estate. The western end of the Outer Dock was originally connected to the Thames at Millwall by an 80 ft (24 m) wide channel. The spoil from the docks formed the area of wasteland known as the Mudchute. A graving dock for ship repairs was constructed at the south-east corner of the Outer Dock (one of 6 originally planned), and later lengthened to 555 ft (169 m).
