From the Wikipedia article
Marsh Lock is a lock and weir situated on the River Thames in the civil parish of Remenham, which is in the English county of Berkshire. The lock is about 1 mile (1.6 km) upstream of Henley Bridge and the centre of the Oxfordshire town of Henley-on-Thames. It is close to the Berkshire bank, but accessed from the Oxfordshire side via two long walkways, the downstream one being near Mill Meadows. The first pound lock was built by the Thames Navigation Commission in 1773. The weir consists of a series of iron watergates running from the lock to the Oxfordshire bank near the mills. It is situated between the two walkways.

Humphrey Gainsborough, a non-conformist minister at Henley Congregational Church, was concerned in the building of the lock. He was an inventor and the brother of the artist Thomas Gainsborough. By 1780, the lock was reported as decaying fast, and in 1787 it was rebuilt of oak. The first…
Visiting
Because the lock is unusually situated on the opposite side of the river to the towpath, a long wooden bridge was built from the Oxfordshire bank to carry the path out to the lock island below the weir, and then back again to the riverbank above the weir. This feature is unique on the River Thames.
