Boveney Lock

This is one of the most popular locks on the River Thames and was first built in 1838. It's much-photographed, partly because it's quite picturesque but also because it lies on a particularly busy part of the Thames. It was rebuilt 60 years after the initial construction, slightly closer to the bank.

Boveney Lock is a lock on the River Thames situated on the Buckinghamshire bank opposite the Windsor Racecourse and close to Eton Wick. Boveney is a village a little way upstream on the same side. The lock was first built in 1838 by the Thames Navigation Commission. The lock was rebuilt in 1898 closer to the Buckinghamshire bank, and a set of boat rollers were installed on the old site.

The weir is almost parallel to the lock, running across from the other side of the lock island.
