most of these buildings and structures were rebuilt over ensuing years, including dummer's original basin and dry dock (today known as no. 1 basin and no. 1 dock). the terrace survived into the 20th century, but was largely destroyed in the blitz along with several others of devonport's historic buildings. just one end section of the terrace survives; dating from 1692 to 1696, it is the earliest surviving building in any royal dockyard.
