These works revealed medieval occupation immediately outside the city walls in the 12th-13th centuries, and features representing 13th-14th century butchery and secondary industrial processing of horn and other bone, and a compost production pit.
A hiatus in activity was evident until the revival of the Liberties in the 17th century, with small-scale tanning and dyeing carried out. Interestingly a 19th century clay pipe kiln was recorded on site from which a large assemblage of pipe fragments, kiln furniture and kiln waste was recovered.
Many of the recorded pipes displayed discolouration or malformation indicating they were discarded mid-way through the kiln drying. Specialist analysis suggest freemasons may have represented substantial clientele.
