An archaeological monitoring exercise (watching brief) was conducted by Network Archaeology during groundworks in the churchyard of All Saints Church, Wellingore, Lincolnshire, between November 2021 and February 2022. The work involved monitoring the excavation of service trenches for the installation of water supply and waste removal for a new toilet, constructed within the north aisle of the church. The watching brief recorded a total of 43 articulated skeletons and large quantities of disarticulated human bone. All the human remains were securely and discretely stored in the church at the end of each working day, as agreed with Rev. Godbold (Rector) and John Ridler (Church Warden). Following consultations with the church authorities, all the recovered remains were reburied within the churchyard. Part of the foundations of the north and south aisles of the church were exposed by the excavation of the trench but were otherwise not impacted. Two medieval walls were discovered to the north of the church tower, possibly forming an early boundary of the churchyard.
