Langton Dock is a dock on the River Mersey, England, and part of the Port of Liverpool. It is situated in the northern dock system in Bootle, connected to Alexandra Dock to the north and Brocklebank Dock to the south. Langton Dock locks provide a working connection to the river; one of the two remaining operational river entrances in the northern dock system.
History
The dock was built by George Fosbery Lyster, and officially opened along with Alexandra Dock in 1881. The dock had been partially in use since 1879.
The Langton Dock Pump House is grade II listed and is on the Victorian Society's list of endangered buildings. The Pump House provided hydraulic power for the dock complex, and maintained water levels within the docks.
In common with some other Liverpool docks, Langton provided dockside accommodation for employees. An octagonal compound, containing seven separate houses built around a central courtyard, was built close to the narrower lock from Canada Basin into Langton Dock. Named Langton Buildings, it enabled key staff to be on hand at any time. There was also a staff flat upstairs in the Pump House.
