Excavations at Portchester Castle have produced evidence of occupation throughout the Saxon period. After the cessation of standard Roman wares and local hand-made types early in the fifth century two Grubenhäuser were built. The contemporary assemblage, assignable to the mid fifth century, included (?) imported carinated bowls and local hand-made grass-tempered wares made in the Roman tradition. Late in the fifth or early in the sixth century stamped Saxon urns appear and probably continue, alongside the grass-tempered tradition, into the seventh century. An association of a grass-tempered pot with an imported glass vessel of eighth-century date shows that the local tradition persisted, but by the middle of the eighth century hand-made jars in gritty fabrics, like those from Hamwih, appear in a substantial rubbish deposit which belongs to the initial occupation of the hall complex. By the tenth century a new style of wheel-thrown pottery, called here Portchester ware, is dominant. It is mass produced and distributed largely from the Isle of Wight to central Hampshire and from the Sussex border to the River Mean. Contemporary forms include imported wares, green-glazed pitchers, pots from the Chichester region, and an assemblage made in a wheel-made continuation of the local gritty-fabric tradition. Portchester ware had gone out of use by 1100 at the latest.
