Evidence was recovered of the presence and perhaps the rituals of mesolithic hunter-gatherers, hitherto unknown official Roman buildings of the first and second centuries and some indication of activity in the late Saxon and medieval periods. An important part of the dig was a programme of geoarchaeological research to study the microstructure of the soils excavated with a view to understanding the activities that led to their formation.
