Sheffield Lock was built between 1718 and 1723 under the supervision of the engineer John Hore of Newbury, and this stretch of the river is now administered by the Canal & River Trust as part of the Kennet Navigation. It has a change in level of 2 ft 2 in (0.66 m).[1]
The lock was built in the early 18th century and was originally turf-sided. It was enlarged in the mid 18th century to cope with larger "Newbury barges"[2] and has 20th century alterations. It consists of brick chamber walls of 11 scalloped bays, with brick coping and has 2 sets of double wooden gates, all with mechanical gate paddle gearing. The lock is Grade II listed,[3] and a scheduled monument.[4]
