Report on excavation of an iron smelting and smithing site datable by radiocarbon determination and analysis of the finds to the late 8th and early 9th centuries. The industrial structures consist of bowl furnaces and associated features of at least three phases, and included a timberframed shelter. Finds include pottery; bronze and iron artifacts, including a bronze key (7th-9th centuries) and strapend (9th-10th centuries), iron strapend with silver inlay (9th century), iron tools, utensils and fittings; and fragments of imported Rhenish lava querns. This and other evidence suggests patronage by an important royal estate. -- AATA
