Excavation confirmed the presence of a substantial boundary ditch on the county border between Norfolk and Suffolk at Fengate Drove, Brandon. The ditch was recut several times, gradually shifting several metres to the north, with the final phase closely matching the modern boundary. The final stages of its infilling appear to have been in the late medieval/post-medieval period but material dating evidence was very limited. By the late 19th century only a belt of trees and possible fenceline marked the boundary.
