P. O. Bar Harbor Me. 219.

The U.S. Post Office-Bar Harbor Main is a historic post office building at 55 Cottage Street. This handsome granite Classical Revival building was one of twelve post offices built in 1909, and is reflective of the government's trend at that time to use classical architecture as a way to express democratic ideals and institutions. The building was listed on the National Register of Historic Places in 1986.
