A metal-working area was excavated under the street adjacent to CAT Building 7. It consisted of several very heavily burnt patches of daub associated with much occupation debris which included fragments of charcoal and 'drips' of copper alloy. Two ovens or furnaces (JF569 & JF611) were also found in this area as well as the bottoms of two stakes or small posts. Quite remarkably, the stumps of these stakes still survived as mineralized wood. They projected upwards by a few centimetres into the gravel of the AD 49-61 period street and thus showed that the structures to which the stakes had belonged had been demolished immediately before the street was laid.<1>
