Dexter and designed by Fuller & Delano.","why_significant":"The building is noted for its opulent Beaux Arts Classical ornament, which sets it apart from neighboring buildings on Main Street. Details include carved limestone cartouches, terracotta window surrounds and swag panels, and a deep pressed metal cornice. It was built for Dexter, who was active in the commercial development of Franklin Square (now Federal Plaza). The architect is identified from a 1900 building notice and assessment records.","narrative":"Located at 538-540 Main Street in Worcester, this five-storey buff brick row building was constructed around 1900 for William H. Dexter, a developer active in the commercial growth of Franklin Square, now Federal Plaza. A September 1900 building notice, a jump in the property's assessed value between 1900 and 1902, and the absence of changes to Dexter's neighboring buildings point to Fuller & Delano as the architects. The two-bay facade carries a notable range of Beaux Arts Classical detail: carved limestone cartouches on the fourth storey, terracotta window surrounds and swag panels on the fifth, recessed bay windows, and a deep pressed metal cornice with dentils. Its ornament is richer than that of its neighbors, and the 1911 city atlas labels it the Enterprise Building. The storefront was altered in the mid-20th century, but the upper facade was recently steam-cleaned and returned to its original appearance. It has served commercial and office uses throughout its history.","period_of_significance":null,"architect_builder":"Fuller & Delano","architectural_style":"Beaux Arts Classical","criteria":[],"status_note":"Recently steam-cleaned and returned to its original appearance; the storefront was altered in the mid-20th century.
