Fremont, Nebraska, was one of the earliest and smallest communities in its state to receive a federally constructed post office. The original sandstone building went up in 1893-95, designed by architect Willoughby J. Edbrooke in the Richardsonian Romanesque style. I love the round-capped columns on the corners. Additions were added in 1910-11 and 1936-37. Still standing, this post office was added to National Register of Historic Places in 1996.
