At a glance: The magnificent 'River Thames' of London
The River Thames is the longest river of England and the second longest in the United Kingdom, after the River Severn. It flows through southern England.
The river gives its name to three informal areas: Thames Valley, Thames Gateway and Thames Estuary.
The river is best known for flowing through Central London providing a stunning backdrop to many of the city's top tourist attractions. It also flows alongside other towns and cities, including Oxford, Reading, Henley-on-Thames, and Windsor.
The 2,000 year old river harbours much of London's history as well as provides ongoing inspiration for artists, musicians and writers.
The Thames is a tidal river, rising and falling as much as 26 ft. between high and low tides. Today, the river is one of the cleanest rivers in Europe.
