As you can see from these photos, Caen Hill Locks are very impressive series of locks and are to be found on the Kennet and Avon Canal near Devizes,
another lovely town in weird Wiltshire.
Each lock is almost on top of the next one and there's plenty of large water roundabouts where the canal boats can move over to let another boat through.
These locks were built alongside a tram road which connected the canal at Devizes.
