The US Post Office—Winchester Main is a historic post office at 48 Waterfield Road in Winchester, Massachusetts. The single-story Classical Revival brick building was built in 1927 and 1928 by John P. Curley for the United States Postal Service. The building features neo-Classical temple fronts on its three principal facades, with a more elaborate projecting instance on the long south-facing facade, where the main entrance is located. The cornice has a simple dentil moulding in limestone; the roof is flat, but there is a raised clerestory section in the center.[2]
