It was to be located to the south of the Royal Albert Dock, which is the large dock at the far right.
context_page_description: The Port of London is that part of the River Thames in England lying between Teddington Lock and the defined boundary with the North Sea and including any associated docks. Once the largest port in the world, it is the United Kingdom's second largest port, after Grimsby & Immingham as of 2012. Usage is largely governed by the Port of London Authority, a public trust established in 1908; while mainly responsible for coordination and enforcement of activities it also has some minor operations of its own.
  The port can handle cruise liners, roll-on roll-off ferries and cargo of all types at the larger facilities in its eastern extent. As with many similar historic European ports, such as Antwerp and Rotterdam, many activities have steadily moved downstream towards the open sea as ships have grown larger and the land upriver taken over for other uses.
context_section_description: London's Docklands had their origins in the lack of capacity in the Pool of London which particularly affected the West India trade. In 1799 the West India Dock Act allowed a new off-river dock to be built for produce from the West Indies and the rest of Docklands followed as landowners built enclosed docks with better security and facilities than the Pool's wharves.
  Throughout the 19th century a series of enclosed dock systems was built, surrounded by high walls to protect cargoes from river piracy. These included West India Docks (1802), East India Docks (1803, originating from the Brunswick Dock of 1790), London Docks (1805), Surrey Commercial Docks (1807, originating from the Howland Great Wet Dock of 1696), St Katharine Docks (1828), Royal Victoria Dock (1855), Millwall Dock (1868), Royal Albert Dock (1880), and Tilbury docks (1886).
  The enclosed docks were built by several rival private companies, notably the East & West India Docks Company (owners of the East India, West India and Tilbury docks), Surrey Commercial Docks Company and London & St Katharine Docks Company (owners of the London, St Katharine and Royal docks). By the beginning of the 20th century competition and strikes led to pressure for amalgamation. A Royal Commission led to the setting up of the Port of London Authority (PLA) in 1908. In 1909 the PLA took control of the enclosed docks from Tower Bridge to Tilbury, with a few minor exceptions such as Poplar Dock which remained as a railway company facility. It also took over control of the river between Teddington Lock and Yantlet Creek from the City corporation which had been responsible since the 13th century. The PLA head Office at Trinity Square Gardens was built by John Mowlem & Co and completed in 1919.
  The PLA dredged a deep water channel, added the King George V Dock (1920) to the Royal group, and made continuous improvements to the other enclosed dock systems throughout the first two thirds of the 20th century. This culminated in expansion of Tilbury in the late 1960s to become a major container port (the UK's largest in the early 1970s), together with a huge riverside grain terminal and mechanised facilities for timber handling. Under the PLA London's annual trade had grown to 60 million tons (38% of UK trade) by 1939, but was mainly transferred to the Clyde and Liverpool during World War 2. After the war London recovered, again reaching 60 million tons in the 1960s.
