Southampton Archaeology is an IFA RO, and has been in existence since 1958, and is now working across central southern England and the Isle of Wight. We provide an archaeology service to the local council, including management of listed buildings and scheduled monuments, and running the local branch of the Young Archaeologists Club. We also work for developers and private individuals from small scale domestic developments to major city-centre shopping centres.
