Located at Iffley Lock on the southern outskirts of Oxford, these boat rollers provide a practical bypass for small craft navigating the change in water levels on the River Thames.

The installation allows punts and rowing boats to be hauled over a set of rollers alongside the main lock, avoiding the need to open the lock gates for small vessels.

The current lock, a reinforced concrete structure, was completed in 1924 on a new site, and the boatslide was built as part of the broader Thames effort to reduce water waste caused by repeatedly opening full-sized locks for lightweight craft.

The rollers remain a functional and historically notable feature of this stretch of the river near the village of Iffley, Oxfordshire.
