From the Wikipedia article
St John's Lock, below the town of Lechlade, Gloucestershire, is the furthest upstream lock on the River Thames in England. The name of the lock derives from a priory that was established nearby in 1250, but which no longer exists. The lock was built of stone in 1790 by the Thames Navigation Commission. The main weir is downstream, just below St John's Bridge, where the River Cole and the River Leach join the Thames on opposite banks. A statue of Old Father Thames by Raffaelle Monti is outside the lock house. The statue was commissioned in 1854 for The Crystal Palace's grounds, was later moved to the traditional source of the Thames at Thames Head, and then in 1974 relocated to St John's Lock. The statue is Grade II listed.

Background
History
The need for a pound lock here arose from the opening of the Thames and Severn Canal upstream in November 1789. It was built by J. Nock in 1790, and in its early days complaints were made of tolls being evaded by bullying bargemen. The first lock house was built in 1830, the lock-keeper being required to give up residence at the Trout Inn in accordance with Commission's rule that lock-keepers should not be publicans. The lock was reported to be in a poor state by 1857 and in 1867 was repaired. In 1905 the lock was rebuilt and a new lock-keeper's bungalow built on the other side of the lock.
