The following are all the contributing resources to the Saint Anthony Falls Historic District in Minneapolis, Minnesota, United States. The District is listed on the National Register of Historic Places, thus these properties are on the NRHP. The "period of significance" of the District was 1858–1941. The district's archaeological record is considered to be one of the most-endangered historic sites in Minnesota.

The Historic District

The City Beautiful idea of progress was to replace old buildings with grander new buildings (like the Minneapolis Post Office, the Great Northern Railroad Depot (1912-1978) and the Pillsbury Library). The Gateway clearance in downtown Minneapolis tore down the now revered Metropolitan Building in 1961. That raised thoughts of historic preservation (thoughts that didn't include the industrial falls area). By then on the west bank most of the flour mills had been torn down, with gravel storage on many of the sites. Waterpower use ended 1960. A few mills operated into the 1960s, with the end of milling, at the Washburn A mill about 1965. In 1969 four of the former flour mills remained standing. For all the historic buildings, use became abandonment, warehousing, light industry, or in one case animal rendering. Second St. had railroad tracks. On the east bank the mighty Pillsbury A mill ended waterpower use 1955, had limited specialty flour milling after 1975, and ended milling in 2003. Three of the four Main Street historic buildings went from commercial to industrial to empty or storage. The National Historic Preservation Act of 1966 promoted historic preservation and created the National Register of Historic Places. Minneapolis created the St. Anthony Falls Historic District, and it was added to the NRHP in 1971. The original filing included 21 existing structures. Minneapolis had decided the riverfront and its history was an amenity that could attract people. In 1980, the Minneapolis Park Board proposed extending the West River Parkway from Plymouth Ave. through the mill district. That triggered a section 106 review. The review found numerous archaeological remains in the mill area, particularly under gravel piles on the river side of the power canal. Remains were also found between the falls and Plymouth Ave. A great deal of public money has been spent in the Historic District, both on public entities, like the Mill City Museum and Mill Ruins Park, but also (including tax credits) on private redevelopment of historic structures. A lot was learned about the Historic District, and the NRHP nomination was amended in 1991 with much more narrative on the significance plus over four times the entities. A lot of the additions were the archeological remains and the individual houses on Nicollet Island. Note that from the falls downstream the river flows substantially to the south east. In this article "south" will mean downstream and "east" is toward the east bank. (In some other sources "east" is downstream.)

St. Anthony Falls Waterpower Area

Use of waterpower at the falls goes back to an 1821 sawmill and an 1823 grist mill, both built by Ft. Snelling. As soon as the area was opened up to white settlement. the land was claimed to get the waterpower rights. The falls was a major saw mill center, then from 1880 to 1930 had the largest flour production in the US. In 1881 the third central station hydroelectric plant in the US was built (for arc lights). Two major hydroelectric plants were built (1894/1911 and 1908) with a third plant (1895) just downstream. One of these plants is still operating. Other industries have also been powered by the falls. Minneapolis developed around these industries. A major part of the District is the remains of these industries (some literally archeological remains). Work restarted 1874 on a tailrace for the Phoenix Mill at 3rd St SE and Main, then downstream under Main St. to just before the walled-off cave and out to the bluff. The tailrace was used by the Phoenix until it closed in 1956. Chute's Cave ( not a contributing resource) is an oval about 100 ft. by 200 ft. under Main St. It is just downstream from the Pillsbury A Mill tailraces. The cave is in sandstone with a limestone roof. The center of the cave has break-down from when the limestone failed 1880, leaving a large hole in Main St. The cave and tunnels still exist. The cave is accessible, but not easily. The entrance to the original tunnel at the bluff is closed but the tunnel can be accessed from the cave. The tunnel has increasingly deep mud away from the cave. The cave and Phoenix tunnel are bat hibernaculum

Nicollet Island Residential Area

The upstream end of Nicollet Island had historic houses of varying architectural styles, and developed as a predominantly middle and working class neighborhood. Plans for redeveloping Nicollet Island were to demolish the houses for a park. The Minneapolis Housing and Redevelopment agency started buying properties in 1968. Residents wanted the houses to remain. In an epic struggle the residents won in 1983.

Associated with the West Bank Power Canal

The falls was the leading US flour milling center from 1880 to 1930. In the following decline many of the west bank mills were demolished in the 1930s. Into the 1960s most of the rest of the west bank mills were demolished or abandoned. Mills were demolished to the ground surface, leaving foundations, drop shafts, tailraces, headraces and sometimes turbines intact. Abandonment of the riverfront meant those remains were not destroyed by new development. Many of these sites are part of the Mill Ruins Park.
