An Archaeological Survey and Watching Brief at Garston Lock,Kennet and Avon Canal

Abstract

Restoration work at the turf-sided Garston Lock by British Waterways in 1993–4, as part of the reopening of the Kennet and Avon Canal, is described. The discovery of a timber head apron of the mid-eighteenth century has provided additional detail on the construction of turf-sided locks at this time. This apron, comprising a base plate, plank floor and side walls as well as a mitre cill, was abandoned when the lock was shortened. Comparisons have been made with a lock of similar construction and date at Monkey Marsh, Thatcham. Garston lock was subsequently rebuilt, possibly c 1854, to the specifications of John Rennie for locks elsewhere on the Kennet and Avon Canal. The turf sides were retained but were reveted with slate, a unique feature for locks on this canal.
