ENN108622 - Northampton Museum and Old Gaol, 2017 (Observation)

{1} The archaeological observation suggests a widespread and deep disturbance and re-deposition of the ground subsequent to the construction of the gaol. Borehole analysis shows a significant depth of loose mixed natural material overlying the geological strata and above this is a layer of mixed backfill containing domestic rubbish and building rubble likely derived from the former brick-built terraced houses which were demolished to allow for the construction of council offices in the late 1930s. In addition to the defunct pipes and drains revealed during groundworks, the car park area is also crossed by a network of active interconnected brick-lined gullies or culverts, each c1m in depth, and these provide further indication as to the extent of general disturbance in the area.
