West Wiltshire District Council’s Warminster Town Centre Conservation Area Character Assessment Informative Document, adopted in April 2007, noted:
West Street was established by 1325 and by the 16th century the town extended as far as what is now 34 Vicarage Street, (Vicarage Street formerly being part of West Street). By 1783 houses stretched along West Street on both sides for 0.8km beyond the High Cross (now The Obelisk in Silver Street), and along Pound Street further than the end of Princecroft Lane.
