Dex Garage, vaults

This series of vaults and tunnels was found during archaeological investigations in 2022 prior to the redevelopment of the site (report 2024/24). They were found following the demolition of the Dex Garage, but were probably associated with the Northumberland Coach and Harness Manufactory (HER10611) which stood on the site previously. The vaults were aligned northeast-southwest and were approximately 5m wide, constructed with parallel sandstone walls, arched brick ceilings and concrete floors. They were connected on the western side by a narrower tunnel running at right angles to them. Further vaulted brick tunnels were found in a trial trench (6) to the southwest.
