The London Borough of Tower Hamlets is a London borough to the east of the City of London and north of the River Thames. Covering a total area of roughly 7.63 square miles, it is in the eastern part of London and covers a great deal of the traditional East End. The London Borough of Hackney lies to the north of the borough while the River Lea forms the boundary with the London Borough of Newham towards the east. Around the other side of the Thames is the London Borough of Southwark to the southwest, The London Borough of Lewisham to the South, and the Royal Borough of Greenwich towards the southeast. The River Lea also forms the boundary between these parts of London historically in Middlesex, with these formerly in Essex.
In line with population estimates produced part way through 2014, the borough features a permanent population of about 284015 people. Many of the tallest buildings in London occupy the centre of the Isle of Dogs in the south of the borough.
The borough is also fairly well-known for being home to the Women's Library in Aldgate, which is Great Britain's main library and museum resource on women and the women's movement, particularly concentrating on Britain during the 19th and 20th centuries. Additionally, a part of the Queen Elizabeth Olympic Park is in Tower Hamlets.
