The building at 280 Broadway has been known by a number of names since it was erected in 1846 (later additions and alterations occurred between 1852 and 1884). Built for the A.T. Stewart Company, it was not only the first commercial building in the Italianate style in the United States but is also considered the country's first department store. The John B. Snook and Joseph Trench-designed marble structure remained home to Stewart's dry goods store until 1876. During the last 14 years, it housed only the wholesale trade, as the retail business had moved further uptown to 9th Street.

Converted into an office building (two new stories were added to the five-story structure), it became the home to the New York Sun newspaper when they purchased it in 1917. Known as the Sun Building, the new owners installed a bronze clock (seen here) at the building's southwest corner.

The paper folded in 1953 and the city took the title during condemnation proceedings. Though the building was to be razed for a planned civic center development, it remained. Substantially renovated between 1995 and 2002, today the building is home to the city's Department of Buildings and lower level retail.
