Locks with guillotine (vertically rising) gates are rare things on the Trust’s canals and are more associated with East Anglian waterways.
We have a few though, the best-known of which is probably the King’s Norton Guillotine Lock, which acted as a stop lock at the junction of the Stratford on Avon and the Worcester & Birmingham canals. It was constructed in the Napoleonic era in 1814 and is now a scheduled monument.
Another is Stamp End Lock on the Witham Navigation in Lincoln. This has its overhead frame handily dated ‘1950’ and is a visually striking, if little known example of the type.
Guillotine lock gates are more complicated than traditional mitre gates; they need more maintenance and those that survive are usually modern and constructed in steel. Earlier formations, like those on the derelict Shrewsbury tub-boat canal, live on only in scant remains and archive photographs, but they never cease to intrigue.
