Between June 2000 and April 2004 four sites within the City of Worcester were subjected to archaeological investigation by Birmingham Archaeology (formerly Birmingham University Field Archaeology Unit) and Mike Napthan Archaeology. The results from these four sites are documented in this volume. One site is located to the northeast of the historic city core at St Martin's Gate. The three remaining sites are located to the north of the city in an area known as The Butts. Archaeological excavations were undertaken at 8-12 and 14-24 The Butts, and an evaluation at 1 The Butts. At all four sites, the stratigraphy is characterised by Roman and post-medieval deposits, with a distinct lack of intervening material. Ditch features relating to Civil War remodelling of the city's defences were located at St Martin's Gate, 8-12 The Butts, and 14-24 The Butts, and it seems that this and later activity was responsible for the disturbance and removal of earlier material.
