Saint Anthony Falls

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.

Mill Ruins Park is a park in downtown Minneapolis, Minnesota, United States, standing on the west side of Saint Anthony Falls on the Mississippi River and running from 3rd Ave. S. to about 9th Ave. S. The park interprets the history of flour milling in Minneapolis and shows the ruins of several flour mills that were abandoned. The park is the result of an archaeological study of the Saint Anthony Falls Historic District. The district was listed on the National Register of Historic Places in 1971. In 1983, a project was being considered to extend West River Parkway along the west side of the Mississippi River in downtown Minneapolis. Scott Anfinson, then the municipal county highway archaeologist for the Minnesota Historical Society, developed a plan to assess archaeological sites along the riverfront. A number of test excavations along the route revealed a wide variety of sites containing items of interest. In the Bassett's Creek area, for example, the foundations of two sawmills and the remains of a railroad roundhouse were found, while near Hennepin Avenue, the investigation found the footings of the Great Northern Railway Union Depot and the tower bases of the first and second Hennepin Avenue Bridges. In the milling district, archaeologists found clues suggesting that there were still extensive remains of the foundations of the mills and waterpower system.The first round of archaeological surveys in the 1980s was intended to save the ruins from destruction as a result of road construction projects. Later, in the 1990s, the focus shifted from environmental impact assessment to exposing ruins for their interpretive value. As the ruins were made visible to the public, the goal was to create assets for education, tourism, and commercial development. The excavations for Mill Ruins Park began in 1998 and continued through 2001. The process also involved stabilizing the remains of the Washburn "A" Mill, which had burned in 1991. The Washburn "A" Mill became part of the Mill City Museum.Along with the remains of about 20 flour mills and other industrial buildings, the park also contains two stone piers and several iron girder piers that held a trestle for the Minneapolis Eastern Railroad. The tailraces from the waterpower canal are also clearly visible, and the water flow has been restored through the canal. Signs posted along the walkways interpret the ruins and the history of the area.

The Third Avenue Bridge is a landmark structure of the city of Minneapolis, Minnesota, United States, originally known as the St. Anthony Falls Bridge. It carries road traffic across the Mississippi River and upper fringes of Saint Anthony Falls. The multi-arched bridge meets with Third Avenue in downtown Minneapolis at its south end, but curves as it crosses the river, and connects with Central Avenue on its north end. The shallow "S" curve in the bridge was built to avoid fractures in the limestone bedrock that supports the bridge piers. The road is also designated Minnesota State Highway 65. Construction began in 1914, and it opened four years later in 1918. The bridge, which uses Melan arches of an open spandrel design, has been modified since that time. The 2,223-foot (667.6 m) crossing was designed by city engineer Frederick W. Cappelen, who also created plans for other similar bridges in Minneapolis such as the Franklin Avenue Bridge. It cost US$862,254.00 at the time of construction.

Owamni by the Sioux Chef, or simply Owamni, is a Native American restaurant in downtown Minneapolis, Minnesota, overlooking the Mississippi River. Owamni's majority Native American staff serves a menu made from indigenous ingredients such as game meats, corn, and wild plants. The restaurant does not serve ingredients that were introduced to the region by Europeans, including butter, dairy, sugar, wheat, chicken, beef, and pork.

Northwestern Consolidated Milling Company Elevator A also known as the Ceresota Elevator and "The Million Bushel Elevator" was a receiving and public grain elevator built by the Northwestern Consolidated Milling Company in 1908 in Minneapolis, Minnesota in the United States. The elevator may have been the largest brick elevator ever constructed (brick construction being relatively uncommon) and ran on electricity. The elevator was the source for the Crown Roller Mill and Standard Mill. Those mills closed in the 1950s but the elevator continued in use for grain storage until the mid 1980s. The building is a contributing property of the Saint Anthony Falls History District listed in the National Register of Historic Places in 1971. In 1987 the elevator was converted to 92,081 square feet (8,555 m2) of office space. That required removing the vertical bin structure and creating floors without destroying the building walls. Before the conversion the building was documented to Historic American Engineering Record standards. Conversion was sensitive to the building history and the building is still a contributing property. About 2015 the building was converted to Millers Landing Senior Living.

The Eastman tunnel, also called the Hennepin Island tunnel, was a 2,000-foot-long (610 m) underground passage in Saint Anthony, Minnesota, (now Minneapolis) dug beneath the Mississippi River riverbed between 1868 and 1869 to create a tailrace so water-powered business could be located upstream of Saint Anthony Falls on Nicollet Island. The tunnel ran downstream from Nicollet Island, beneath Hennepin Island, and exited below Saint Anthony Falls. During construction of the tunnel, on October 5, 1869, the river broke through the thin layer of limestone separating the river's bed from the tunnel. The rushing river scoured the tunnel, caving in parts of Hennepin Island and causing the earth supporting Saint Anthony Falls to collapse upstream. There was serious concern that the riverbed would crumble and reduce Saint Anthony Falls to a long set of rapids. Within a few weeks, dams were built to divert the river and stop Saint Anthony Falls from being washed away. The fix was temporary as the 1870 spring floods damaged some of the new dams and swept away more of Hennepin Island. The final fix for the tunnel disaster was a concrete dike constructed by the United States Army Corps of Engineers. The Corps also built a protective sloping wood timber apron to create an artificial falls which remain the only major waterfall on the Mississippi River. The Eastman tunnel is a contributing resource to the St. Anthony Falls Historic District. The District is on the National Register of Historic Places The site of the tunnel is about a mile upstream from site of the I-35W Mississippi River bridge that collapsed in 2007.

The Great Mill Disaster (also known as the Washburn A Mill explosion) occurred in Minneapolis, Minnesota, United States in 1878. The disaster resulted in 18 deaths. The explosion occurred on the evening of Thursday, May 2, 1878, when an accumulation of flour dust inside the Washburn A Mill (the largest mill in the world at the time) led to a dust explosion that killed the fourteen workers inside the mill. The resulting fire destroyed several nearby mills and killed a further four millworkers. The destruction seriously impacted the city's productive capacity for flour, which was a major industry in the city at the time. Following the blast, Cadwallader C. Washburn (the mill's owner) had a new mill, designed by William de la Barre, constructed on the site of the old one. This building was also later destroyed, and today the building's ruins are a National Historic Landmark and operated as part of the Mill City Museum.

The Saint Anthony Falls Laboratory (former name: Saint Anthony Falls Hydraulic Laboratory), or SAFL, is a research laboratory situated on Hennepin Island in the Mississippi River in Minneapolis, Minnesota, United States. Its primary research is in "Engineering, Environmental, Biological, and Geophysical Fluid Mechanics". It is affiliated with the University of Minnesota's College of Science and Engineering. Research is conducted by graduate students and faculty alike using the 16,000 square feet of research space and 24 different specialized facilities. The laboratory is unique in that its location next to Saint Anthony Falls allows it to use the hydraulic head from the waterfall to provide water for many of the experiments. The experiments performed at the laboratory are varied, and may include: Contract civil and environmental engineering work, such as dam construction and removal Understanding river system dynamics Work with oil exploration to characterize deposits in deltaic systems Work to understand the interactions between fluid flow and the ecology of rivers Work to understand cavitation in fluids in order to build better propellersThe Saint Anthony Falls Laboratory is also the headquarters of the National Center for Earth-surface Dynamics, a National Science Foundation Science and Technology Center.The laboratory is a contributing resource of the Saint Anthony Falls Historic District which is listed on the National Register of Historic Places.

The Mill District is a neighborhood within Minneapolis, Minnesota, United States, and a part of the larger Downtown East neighborhood. The neighborhood contains several former flour mills left over from the days when Minneapolis was the flour milling capital of the world. With almost none of the mills still active, a number of these have been converted into condominiums leading to a revitalization of the neighborhood.Its approximate boundaries are the Mississippi River to the north, the I-35W Mississippi River bridge to the east, Washington Avenue to the south, and 5th Avenue to the west. It is bounded by Downtown West as well as the rest of the Downtown East neighborhoods. The Marcy-Holmes neighborhood is on the other side of the river, but there is no direct automobile connection between the two neighborhoods. There is a pedestrian and bicycle connection via the Stone Arch Bridge. The area also includes several cultural institutions, including the Guthrie Theater, the Mill City Museum as well as the MacPhail Center for Music. The area includes Mill Ruins Park, the new Gold Medal Park as well as the headquarters for the McKnight Foundation.

The Chicago, Milwaukee, St. Paul and Pacific Depot Freight House and Train Shed (commonly referred to as the Milwaukee Road Depot), now officially named The Depot, is a historic railroad depot in downtown Minneapolis, Minnesota, United States. At its peak, the station served 29 trains per day. Following decline, the station was closed and eventually adapted into various other uses.

Merriam Street Bridge is a truss bridge that spans the east channel of the Mississippi River between Nicollet Island and the east bank of the river in Minneapolis, Minnesota. The bridge was originally built in 1887 by King Iron Bridge Company as one of the four spans of the Broadway Avenue Bridge. When the Broadway Avenue Bridge was reconstructed in 1987, one span was preserved and moved to Nicollet Island. The truss span is actually decorative; the bridge is supported by a beam from underneath. The original Broadway Avenue Bridge was one of the fanciest bridges on the Mississippi River. It featured finials on each top corner and a band of scrolls, crosses, and lines between them. The horizontal struts and guard railings used X-shapes as a pattern. Each end of the bridge has a hexagonal cast iron plate embossed with the date and the designer of the bridge. The bridge now serves as a connector between parkland on Nicollet Island and the Saint Anthony Main development on the east bank, allowing good opportunities for visitors to stroll across the river.
