The United States Post Office at 209 East Portage Avenue in Sault Ste. Marie, Michigan, is an historic building which has served various purposes since its construction in the early 20th century. The building was listed on the National Register of Historic Places on September 9, 1977.HistoryIn 1822, Fort Brady was constructed on this site. In 1893, Federal troops abandoned the fort in favor of new location closer to the center of the Soo canal. The old fort site was reserved for the construction of a public building, and was used as a public commons until 1908, when Congress appropriated $150,000 for the construction of this Federal Building.The building was constructed in 1909-1910 of limestone from a Bedford, Indiana quarry, using a design by James Knox Taylor, then Supervising Architect of the U.S. Treasury. It served for decades as a post office and a courthouse of the United States District Court for the Western District of Michigan, with the court meeting there from 1912 until 1941.In 1992, the Sault Foundation for Culture and History acquired the building from the government, which had built a new facility for the courts, and converted it into the River of History Museum. This facility was to preserve and promote "the history of the St. Mary's River system". On July 1, 2009, the museum relocated, moving its exhibits to a new site. As of 2010, the building was renovated for use as office space as the City Hall.
