Four Canal Locks

Four Canal Locks between Stanley Dock and Leeds and Liverpool Canal, South of Lightbody Street 
Circa 1848
Grade II

Although the canal had been in partial use since 1774 and was completed through to Leeds in 1816, a series of disputes prevented a direct link to the docks being formed until 1848. 

When agreement was finally reached, it was stipulated that the four locks should be designed by Hartley, and the result is the only all-granite canal locks in the country. 

The handsome brick viaduct, which crosses the locks, carried the Liverpool and Bury Railway (now serving as part of the Merseyrail system) and was constructed at the same time as the locks
