An archaeological excavation in central Salisbury revealed continuous occupation from the 13th century to modern times. Several standing walls were constructed from chalk blocks and formed a two-cell shaft-and-pit garderobe of High Medieval date. This was replaced by a later medieval well and truncated by a post-medieval boundary wall. The disuse fills of the garderobe, as well as clusters of intercutting cess or rubbish pits, of later medieval date, contained valuable information on the site's economy and the inhabitants' diet. A single sherd of late Bronze Age pottery recovered from a heavily truncated pit within a pit cluster may be indicative of limited prehistoric activity in the area. The site is considered to represent a single back-yard plot in the medieval period, sub-divided in post-medieval times. This Occasional Paper contains reports on locally significant stratified and well-dated assemblages of pottery, metallic finds, animal bones and plant remains which will form a baseline for future research into the medieval city, whose archaeology, has previously been surprisingly patchily documented.
