Excavation in 2000-2002 carried out as part of the Channel Tunnel Rail Link found an early medieval sunken-feature building close to the head of the Ebbsfleet and within the rear part of the abandoned Roman sanctuary complex. The pit was sub-rectangular in plan, measuring 3.60 m by 2.40 m by 0.25 m deep. Two post-holes were identified within the pit, one at either end, both measuring approximately 0.30 m wide and 0.35 deep. The fills of the post holes contained a number of finds including a complete double-sided composite comb, pottery and animal bone. (1)
