Archaeological monitoring, excavation and recording was undertaken by AC archaeology in November 2020, on behalf of Ferriby Land, during the redevelopment of the Grade II Listed 24 High East Street, Dorchester, Dorset. Excavations for new services within and outside the rear warehouse were monitored. Within the building a flagstone floor surface, contemporary with the warehouse of c.1820-1840, was exposed. Foundations, an internal floor surface, and landscaping deposits associated with the addition in the early 20th century of a side passage to the warehouse were also exposed. No earlier, dateable deposits were exposed, and no finds recovered.
