Excavation in 2000-2002 carried out as part of the Channel Tunnel Rail Link found a large pit located close to and likely associated with an Anglo-Saxon sunken feature building, to the south of the Springhead Excavations. It was located 5m to the north of the SFB and was sub rectangular, probably comprising two intercutting pits, measuring 4.0 m by 3.0 m and up to 1.2 m deep. The sides generally sloped at c 45° and there was a 0.25 m deep post-hole in the base at the southern end. The lower fills appeared to comprise re-deposited or slumped natural brickearth sealed by a charcoal-rich soil which contained a relatively large quantity of pottery and other finds probably representing occupation debris. This is turn was sealed by a further deposit representing a mixture of refuse disposal and natural silting. (1)
