An archaeological evaluation was carried out during September 2018 and January 2019 at 9 Harbidges Lane, Long Buckby, Northamptonshire, in advance of proposal for residential development of the site. Although limited in scope, the investigation revealed features dated to the C12 and mid-C13. On the west side of the site they comprised a ditch interpreted as a former boundary enclosing a probable small timber-framed structure seemingly aligned perpendicular to Harbidges Lane and on the southern edge of the site a single right-angled feature, possibly an enclosure ditch, produced C12 and mid-C13 pottery. The evidence, in combination with other discoveries in the area suggests that that site is part of a settlement comprising tenement plots that became established along both sides of Harbidges Lane during the period of occupation associated with the castle site situated immediately to the east. The remains at 9 Harbidges Lane lie immediately north of the castle bailey.
