St John the Baptist, Chelveston obtained planning consent for the resurfacing of the driveway to the churchyard and the establishment of a new path giving access from the north-east corner of the churchyard to the south porch of the church, together with a new mains water supply to the church from Caldecott Road. The archaeological works comprised the monitoring and investigation of a narrow, c.0.8m-deep and c.120m-long, machine-excavated service trench that ran from Caldecott Road to the west end of the church's south aisle. The trench revealed that separate graveyard soil layers exist to a considerable depth. Only a small patch of natural geology was exposed south of the church. Four burials and an additional probable burial were identified. None contained any artefacts and their precise date is unknown. The trench along the access path from Caldecott Road revealed evidence for earlier surfaces and for consolidation of the entrance to the graveyard. The only part of the church foundations exposed by the service trench was at the south-west corner of the porch. The foundation was 0.6m deep and extended 0.3m beyond the porch wall; it comprised roughly hewn, unmortared limestone blocks. A loose group of large stone blocks recorded close to the south aisle is judged to be a probable demolition deposit. Layers either side of the graveyard entrance produced a small quantity of relatively unabraded Roman pottery. These are residual artefacts, derived from a Roman site in the vicinity. Their presence accords with earlier records of the discovery of Roman pottery within the churchyard and with known contemporary sites within the village.
