Archaeological investigations on the site of Cabot House and the adjacent car park comprised excavation, a borehole survey and a watching brief in advance of the redevelopment for offices. Evidence from the borehole survey showed that rising sea levels affected the environment at the Cabot House site at a slightly later date in the Neolithic period than other sites in the central Bristol area, but there was no direct sign of human impact from this period. In the post-medieval period, the area was part of the 'Bishop's Park', which was infilled and levelled in advance of suburban streets and housing development in the late 18th-century. Excavation revealed the plans and internal details of some properties on St George's Street, Deanery Road and College Street, and these are supplemented by documentary research into the character of the properties and their later histories.
