On Grand Street in Waterbury is a white marble Art Deco post office, built in 1931-1932. The building was designed by George Oakley Totten. The facade of the Post Office features eleven relief panels illustrating the history of communication and transportation. In 1971, the building was renamed the John S. Monagan Federal Building and expanded in the rear to accommodate the District Federal Court and several federal agencies.

This is a beautiful building. Incidentally, there’s an Internal Revenue Service office inside as well – after looking it up I determined the IRS have a ton of local offices in various towns and cities across the country. Not sure if they’re housed in this one since it’s a federally-owned building, at least to my knowledge – it’s owned by the USPS anyway. The building and land are currently valued at $31,239,680 – For more info see this page http://gis.waterburyct.org/GIS/propertyresults.asp?MBL=0294-0273-0034
