This is a fascinating book for anyone with an interest in the history of one of Great Britain's most important rivers. The River Thames takes its name from the Middle English Temese, which is derived from the Celtic name for river. Originating at the Thames Head in Gloucestershire, it is the longest river in England, flowing a total length of 236 miles, out through the Thames Estuary and in to the North Sea. On its journey to open water it passes through the country's capital, London, where it is deep enough to be navigable for ships, thus allowing the city to become a major international trade port.
