How to get there
Culham lock can be reached from the road at Sutton Bridge, or on foot across the fields from Sutton Courtenay.
There's a small car park right by the lock.
Culham lock lies in Oxfordshire, near the small village of Culham. It is one of the two deepest locks on the river, the other one being Sandford. The adjacent locks are Abingdon Lock, 4.15 km (2.58 mi) upstream, and Clifton Lock, 4.52 km (2.81 mi) downstream.
The lock was built in 1809 as a welcome replacement for the pound lock by Sutton Mill, which was difficult to negotiate and the tolls charged by the millers were high. However, the new lock isolated Sutton Courtenay from the main river, impacting its trade.
Around the lock
The lock is a tranquil place to stop and watch the boats pass through, and there are several benches beneath majestic trees offering plenty of shade on hot days. You also get a nice view of the picturesque Sutton Bridge extension.
Beyond the lock
From the lock, you can walk along the river bank, or across the fields to Sutton Courtenay, for example. Also nearby, towards Abingdon, is Culham Bridge, a mediaeval bridge crossing the River Thames near Culham.
