Following on from the evaluation work in the spring of 1997 at the site of the former Holy Trinity School, it was decided to fully excavate a large area in the most archaeologically sensitive part of the site. This work in the north western corner of the site revealed a number of features. A single shallow pit was dated to the Late Bronze Age to Iron Age. A total of 25 east-west orientated graves were recorded, five of which had been located and excavated by Dartford District Archaeological Group during previous work on the site. Some of the graves were associated with grave goods, which along with the burial rite, suggest a 7th to early 8th century date. One of the female inhumations was buried with the remains of a foetus or neonate. Two parallel east to west running linear features have been interpreted as beam slots for a small building, dated to the 11th to early 12th centuries. Several postholes were found in proximity to this structure and have been associated with it. To the north east of the building a single pit has been dated to the 11th century. A small part of a possible medieval boundary ditch was recorded in the north west corner of the site, dated to the 13th century.
