Aldermaston Lock was built between 1718 and 1723 under the supervision of the engineer John Hore of Newbury. It was originally turf-sided, but enlarged in the mid-eighteenth century and given scalloped brick walls. It was altered in 1984 when the walls were raised to the full height of lock as part of its restoration.[1] The original height of the scalloped walls is marked by a line of blue bricks.
It was originally called Brewhouse Lock because Strange's Brewery stood beside it.[2]
Along with the length of the canal, the lock is the responsibility of the Canal & River Trust. It has a rise/fall of 8 feet 11 inches (2.72 m).[3]
