Site Assessment = Now a natural history museum. All Saints is in the Roman forum-basilica complex, probably over the E range. 'It would be surprising if the foundation at least, did not make use of the underlying Roman walls (as with St Nicholas's)'. No current threats but should the opportunity arise there should be detailed examination of the fabric and excavation to assess possible reuse of the Roman structure.<3>
