As the town of Westborough emerged from rural agricultural community to commercial center, connections to Worcester and Boston via rail service opened the town to prosperity. As businessmen accumulated wealth, these merchants built stately homes to showcase their position in the community. Before the Civil War, the Greek Revival style was ever-popular in Westborough, even though the style was already waning in popularity in larger cities. The Gilmore-Mason House on Church Street, is an excellent example of the Greek Revival style in a temple form. The form is seen in this house at the facade, with a portico of four two-story Corinthian columns supporting the pediment above. The house was built for George A. Gilmore and later sold to Alonzo W. Porter, an inventor, who would later move to New York. By the early 20th century, the residence was the home to Joseph S. Mason, a manufacturer who operated a weaving mill in Westborough.
