Pits and Boots derives from excavations carried out in 2007-8, in advance of an extension to the Bon Accord Centre in Aberdeen, that uncovered the backlands of an area that would have formed part of the industrial quarter of the medieval town. The site is well-dated by dendrochronology, augmented by artefactual evidence, and indicates activity from the late 12th century AD into the early modern period, with a particularly intensive period in the 13th century. Structural evidence consists primarily of the backland boundaries, hearth/ovens, several wood-lined wells and many large pits. It is the contents of these pits and wells which forms the core of this monograph. The waterlogged conditions within the pits and wells has meant that a remarkable assemblage of organic remains including leather, wooden artefacts, textiles, animal pelts, fibres, and cordage has survived. The leather assemblage is the largest ever to be found in Scotland and has revealed a range of activities associated with the use of animal hides, from hide processing to tanning and shoemaking. The wood assemblage is also extensive and includes bowls, platters, coopered vessels and tools. Metalwork, crucibles, clay mould fragments and ceramics all testify to the industrial nature of the area, while the large quantities of animal and fishbone demonstrate that butchery on an industrial scale took place in the area. The excavation charts the changing nature of this once-peripheral area of Aberdeen, from an industrial zone in the medieval period, to horticultural and domestic spaces in post-medieval times, and has thus greatly enhanced our knowledge of Scottish urban development.
