The United States Post Office, located at 1701 Charleston Ave., is the former main post office of Mattoon, Illinois. The post office was constructed in 1913 by Mangnus Yeager & Son, a building company from Danville, Illinois. The building was designed in the Classical Revival style and features Renaissance Revival influences; James K. Taylor was the Supervising Architect for the building. The front of the building features seven arches in front of a portico containing the entrance, which is located at the top of a marble staircase. The three central arches are topped by a carved frieze, and marble cartouches separate each pair of arches. The building served as Mattoon's post office from its construction until 1980, when a new post office opened.[1]
The building was listed on the National Register of Historic Places in 1979.
