Document 3: Downings Roads Moorings: Downings Roads Moorings is a mooring for barges on the River Thames near Tower Bridge that is home to a small community of houseboat dwellers in Central London. In 2003 and 2004, they were threatened with eviction by Southwark Council. The members of the community appealed. The then Mayor of London Ken Livingstone commented in a letter to Southwark Council that "The principle of retaining the moorings is supported by the London Plan policy 4C.19 and supporting text contained in paragraphs 4.117 and 4.118. The mix of uses proposed for these moorings should be seen as broadly acceptable in the context of a multi functional Blue Ribbon Network as long as there are appropriate amenity and environmental safeguards in place.". Their eviction was quashed in late 2004.
Document 4: Tower of London: The Tower of London, officially Her Majesty's Royal Palace and Fortress of the Tower of London, is a historic castle located on the north bank of the River Thames in central London. It lies within the London Borough of Tower Hamlets, separated from the eastern edge of the square mile of the City of London by the open space known as Tower Hill. It was founded towards the end of 1066 as part of the Norman Conquest of England. The White Tower, which gives the entire castle its name, was built by William the Conqueror in 1078 and was a resented symbol of oppression, inflicted upon London by the new ruling elite. The castle was used as a prison from 1100 (Ranulf Flambard) until 1952 (Kray twins), although that was not its primary purpose. A grand palace early in its history, it served as a royal residence. As a whole, the Tower is a complex of several buildings set within two concentric rings of defensive walls and a moat. There were several phases of expansion, mainly under Kings Richard the Lionheart, Henry III, and Edward I in the 12th and 13th centuries. The general layout established by the late 13th century remains despite later activity on the site.
