Just across the St. Lawrence River from Canada, in northern New York State, the Odgensburg post office stands at 431 State Street. It was built between 1867 and 1870, designed by Alfred B. Mullett, for federal postal, customs, and court facilities. The Classical Revival building is built of sandstone and limestone.
This early postcard (I love the sky) shows the post office with its original dome, which seems to have been removed sometime around 1910. The building was refurbished in 2003, and is still home to the post office.
