Every spring since 2014, teams of students from the University of Southampton's Department of Archaeology have spent several weeks at Old Sarum on a research project, as part of their training programme. Starting in early April 2017, a fourth group of students will be continuing the geophysical survey of the area and they are expected to be working in some of the fields between Old Sarum and Stratford sub Castle.
An integrated strategy incorporates different surveying methods including earth resistance survey, magnetometry, Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT). The objective is to produce a new topographic interpretation for Old Sarum and Stratford sub Castle, integrating LiDAR data with an on-site topographic survey of visible features. 
All of these methods are non-intrusive to the landscape and there won't be any open trenches to view. In previous years the staff who have accompanied the students have been happy to talk to on-lookers and explain some of the process. The University of Southampton has also encouraged local residents and archaelogical groups to participate in the Old Sarum Landscapes Project and a study day was held at the University in January 2017.
UPDATE 10 April. This week several local volunteers will be taking part in the project. Check the Gallery for photos of their activities.
Results of the surveys from earlier years have revealed the existence of a network of medieval streets and numerous buildings in the area between Old Sarum and Stratford sub Castle.
The Friends of St Lawrence Church Trust has arranged for expert guest speakers to deliver an illustrated talk to share and interpret some of these discoveries:
