Watching brief by R Poulton of SCAU during the construction of an extension and related works revealed evidence of 18th century and perhaps earlier activities. A substantial wooden channel recorded within one of the extension trenches may be best explained as part of a development of more sophisticated arrangements for the supply of water to houses, or for use in industrial activities. The wood could not be accurately dated by dendrochronology, as weaknesses in the county’s chronologies suggest that the sample was felled before c1200, or more likely after c1650. A brick and stone culvert on the same alignment as the wooden channel may represent a later arrangement for the same purpose, or be part of drainage arrangements which were wholly or partially made necessary following the disuse of the channel.
