Aynho Weir Lock No. 33 is a shallow lock of unusual construction.
It was built in 1790 and promptly enlarged!
Aynho Weir Lock No. 33 is situated adjacent to Accommodation Bridge No. 188 on the Oxford Canal. Its primary purpose was to protect the Oxford Canal from any surge in the River Cherwell, which crosses the canal at the same level on the other side of the bridge.
It was rapidly enlarged, after construction in 1790, with a maximum breadth of 20ft; this compensates for its very small fall (less than 1ft).
The alteration ensures that when the lock is emptied, sufficient water passes into the canal to fill the next lock, which is Somerton Deep Lock with a 12ft fall, 2 miles south.
