Phoenixville Post Office

Built as a store around 1825 in Phoenixville, Connecticut, this structure was expanded to it’s present size about 1830 and changed little after that (the original "swirl" and "dab" paint treatment is still visible on the walls). Until 1884, the building served as both general store and drugstore-apothecary and a post office was moved into one end. The building, which remained primarily a post office until 1910, was run by Monroe Latham, a city selectman and local politician, and his wife, who served as post mistress.
