SDO19753 - Corn Exchange Extension, North Square, Dorchester, Dorset: Archaeological Observations and Recording during Groundworks, October 2021

Terrain Archaeology carried out archaeological observations and recording during the piling for a new extension to the Corn Exchange, Dorchester and its associated services. The piling observations revealed that the natural chalk was below a layer of probable post-medieval garden soil buried by terrace deposits for the nineteenth century Market House. A well of possible medieval date was adapted by the addition of a chute in the post-medieval period, perhaps to adapt it as a drain or soakaway within the Market House.
