It reflects the growing importance of corporate building during the city's last major boom. Its New York architects are typical of the city's large office blocks of 1900-1920.","narrative":"Rising eleven storeys above Main Street in Worcester, the Park Building is a steel-frame office block faced in dressed limestone and built in 1914-1915 for the Park Trust Company. The first two floors have a metal and plate-glass storefront with cast classical ornament, partly altered in the mid-20th century. The third floor has evenly spaced windows between carved limestone panels beneath a cornice. The middle floors are plain, while the tenth and eleventh floors are treated as a loggia with engaged Tuscan columns, topped by a cornice and copper cresting. It was the largest of several downtown office blocks built by corporations and holding companies in the early twentieth century, and it dominated the skyline until Worcester Center was built in the late 1960s. Unlike earlier commercial buildings, it was built for a corporation rather than an individual. Its New York architects, Cross & Cross and D.H. Burnham, reflect the city's habit of hiring designers experienced in skyscrapers.","period_of_significance":null,"architect_builder":"Cross & Cross of New York; D.H.
