This project consisted of a major archaeological watching brief and excavation programme, conducted across an extensive part of the maritime and water-front areas of this important historic town, ahead of major road construction and sewer trenching, between the summer of 1991 and the spring of 1993. There were 21 areas of archaeological investigation: the second was Archcliffe Fort; an 17th-19th century artillery fort. An extended watching brief; limited excavation; salvage recording; building recording and palaeo-environmental sampling was undertaken, ahead of, and during, road-building and sewer trenching. Features uncovered and investigated included evidence of Prehistoric occupation under north rampart.

Within the seventeenth century walls of Archcliffe Fort a small assemblage of prehistoric struck flints and calcined flints was recovered from an undisturbed deposit over the natural brickearth, exposed in a new sewer trench. This lithic material is clearly indicative of prehistoric settlement on the Archcliffe promontory, probably during the late Neolithic or Bronze Age period.(1)
