The Post Office at 265 Main Street in Danbury was erected in 1915-1916. It was designed by Oscar Wenderoth, who was Supervising Architect of the U.S. Department of Treasury from 1912 to 1915, during which time he designed many federal building throughout the country. The Georgian Revival building, which has a stained oak interior, served as the city’s main post office until 1985, when a new main post office facility opened on Backus Avenue. Mail processing operations moved to the Backus location in 2007 and the Main Street office has continued as mostly a retail facility that also accepts mail and has over 800 P.O. boxes. With the Postal Service utilizing only a small portion of the large building, there have been concerns in recent years that the Main Street office might close. Local residents have voiced their support for a post office downtown, if not in the 1916 building, than at an alternative location on or near Main Street.
