Four seasons of excavation and structural study in St. Peter's Church have revealed a complex sequence, beginning with domestic occupation of the Pagan Saxon period, followed by a Middle Saxon settlement enclosure with adjacent cemetery of Christian character. In the later tenth century a three-celled turriform church was built in the cemetery, after the exhumation of graves covering its intended site. Related features in the cemetery include the foundation of a large free-standing cross, a group of wells and an oven, probably for baking bread, all grouped to the east of the chancel. Some of the pre-Conquest graves yielded evidence of probable barkwood coffins built with clenches and roves, while some twenty further graves contained rectangular timber coffins in varying states of preservation. Several were in near-perfect condition and have yielded exceptionally good evidence for techniques and tools employed by Anglo-Saxon carpenters.
The extant Saxon and medieval fabric of the church has been recorded in considerable detail, providing an insight into building and scaffolding methods, particularly of the tenth century. Excavation has revealed the complex development of the medieval church and its internal layout; and 1,326 graves, spanning a millennium, have been investigated.
