What was the first addition to the Town Quay chronologically?, Context: Town Quay is the original public quay, and dates from the 13th century. Today's Eastern Docks were created in the 1830s by land reclamation of the mud flats between the Itchen & Test estuaries. The Western Docks date from the 1930s when the Southern Railway Company commissioned a major land reclamation and dredging programme. Most of the material used for reclamation came from dredging of Southampton Water, to ensure that the port can continue to handle large ships.
