Thames Head


Thames Head is the traditional source of the River Thames. While the Environment Agency, the Ordnance Survey, and other authorities have the source of the Thames as Trewsbury Mead, others hold that the true source of the Thames is at Seven Springs, Gloucestershire, the source of the River Churn, which is a tributary of the Thames.

Description

Thames Head is in Gloucestershire, in south west England, and is identified as the source of the River Thames, the major river which runs through the centre of London. It is in a meadow known as Trewsbury Mead near the village of Kemble and the town of Cirencester. The elevation of the source is above sea level.

Monument

A monument beneath an ash tree bears the inscription:
A nearby basin of stones marks the spring, however, there is usually only water during a wet winter.

Controversy

The claim that this site is the source of the River Thames is disputed. The Environment Agency, the Ordnance Survey and other authorities have the source of the Thames as Trewsbury Mead. Others hold that the true source of the Thames is at Seven Springs, Gloucestershire, some farther north, and east of Gloucester. Seven Springs is officially the source of the River Churn, which is a tributary of the Thames that joins at Cricklade. As it is further from the mouth of the Thames than Trewsbury Mead, the adoption of Seven Springs as its source would make the Thames the longest river in the UK.
