Work in connection with conversion of buildings at Archcliffe Fort for use by St. Martin's Emmaus Community in 1996 and 1997. Along with evidence of demolished 18/19th century fort buildings and late Neolithic-Bronze Age activity, nine medieval pot sherds were found ranging in date from the later twelfth - to mid fourteenth centuries. Five of the pieces were of Tyler Hill sandy ware. The two later sherds, c.1275 - 1325/50, could possibly be contemporary with the documented watchtower that stood on the promontory.
