In 1893, Federal troops abandoned the fort in favor of new location closer to the center of the Soo canal.

The Old Federal Building is a rectangular three story limestone Renaissance Revival structure on a raised granite foundation.

The first floor is built of smooth coursed limestone with horizontal recessed joints, above which is a carved frieze.
