Twelve test pits were excavated in Walberswick in May 2015 by 48 Year 8 and 9 students from Sir John Leman School, Alde Valley Academy, Bungay High School and Ormiston Denes Academy. The test pitting was part of the Higher Education Field Academy (HEFA) programme undertaken by Access Cambridge Archaeology (ACA) in East Anglia, which aims to raise the aspirations, enthusiasm and attainment of 14-17 year-olds with regard to higher education by making a valuable contribution to current academic research at the University of Cambridge, and in the process contribute to the university's Currently Occupied Rural Settlements (CORS) research into the development of rural communities and settlements in the past.
The 2015 excavation sites were widely distributed across the village and complemented the nine test pits that were excavated in 2013 and the nine from 2014, bringing the total now excavated in the village to 30. For the first time during the test pitting Roman pottery was recorded in the west of the village and opposite the church that overall indicates some level of activity during this period. An additional four test pits in 2015 yielded Late Anglo Saxon pottery, which with the previous Late Saxon pottery already recorded, indicates a cluster of activity forming around the green and extending southwest along The Street. This settlement continued to thrive into the medieval period as noted from previous years excavations, and the pottery evidence continues to suggest that Walberswick did not decline in the later medieval period after the Black Death, potentially due to its status as a coastal trading settlement. In the post medieval period the village may have developed into the small fishing village that is still seen today.
