Hennepin Island Hydroelectric Plant

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 Stone Arch Bridge is a former railroad bridge crossing the Mississippi River at Saint Anthony Falls in downtown Minneapolis, Minnesota. It is the only arched bridge made of stone on the entire Mississippi River. It is the second oldest bridge on the river next to Eads Bridge. The bridge was built to connect the railway system to the new Union Depot, which at that time was planned to be built between Hennepin Avenue and Nicollet Avenue. The bridge was completed in 1883, costing $650,000 at the time ($18.9 million today). 117 Portland Avenue is the general address of the historic complex. Located between the 3rd Avenue Bridge and the I-35W Saint Anthony Falls Bridge, the Stone Arch Bridge was built in 1883 by railroad tycoon James J. Hill for his Great Northern Railway, and accessed the former passenger station located about a mile to the west, on the west bank of the river. For a time, the bridge was dubbed "Hill's Folly" until the value of Hill's new bridge as a passenger rail link became evident.The structure is now used as a pedestrian and bicycle bridge. It was added to the National Register of Historic Places in 1971 as a part of the Saint Anthony Falls Historic District, (District #71000438). The bridge was designated as a National Historic Civil Engineering Landmark in 1974.

The Pillsbury A-Mill is a former flour mill located on the east bank of the Mississippi River in Minneapolis, Minnesota. It was the world's largest flour mill for 40 years. Completed in 1881, it was owned by the Pillsbury Company and operated two of the most powerful direct-drive waterwheels ever built, each capable of generating 1,200 horsepower (895 kW). In 1901 one of the turbines was replaced with a 2,500 horsepower one. Both the mill and its headrace tunnel are contributing resources to the St. Anthony Falls Historic District, which is on the National Register of Historic Places. The mill is also independently on the NRHP. The mill was named a National Historic Landmark in 1966 and has since been converted into resident artist lofts.

The Minneapolis–Saint Paul International Film Festival is a springtime film festival in the U.S. state of Minnesota that has been held since 1981. It began as the Rivertown Film Festival in Stillwater by Al Milgrom of Pine City and eventually grew to become the largest film event in the Upper Midwest, with an annual attendance that exceeds 40,000. Historically lauded for being one of the world's finest showcases of Scandinavian films, the festival features an eclectic lineup of films from more than 70 countries annually. Locally produced material is also highlighted through a series called Minnesota Made, or MN Made. The Festival is organized by the Film Society of Minneapolis St. Paul, a 501(c)(3) non-profit film exhibition organization operating out of the St. Anthony Main Theatre on the Mississippi River in downtown Minneapolis. Several other area theaters also participate in the film festival. In December 2014, the Film Society attracted national attention when it became one of the few distributors in the country to exhibit the controversial film The Interview after Sony Pictures reinstated the film's theatrical release after scrapping it amidst threats from hackers purportedly associated with the North Korean government.

Saint Anthony Main refers to an area of buildings with multiple owners located on Main Street across from St Anthony falls in the Nicollet Island/East Bank, Minneapolis section of Southeast, Minneapolis in the U.S. state of Minnesota. Commonly the area is associated with Northeast, Minneapolis as it is actually northeast of downtown on the east side of the Mississippi River. It opened as a festival marketplace in the 1980s. The area underwent a resurgence during the condominium boom in the early 2000s with several condo projects built in and around the area. It is now home to a movie theater, four bars and restaurants, a small cafe, design firms, and a Segway tour operator.

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.

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 Industrial Exposition Building was located in Minneapolis, Minnesota. The building stood from 1886 to 1940 and was briefly the tallest structure in Minneapolis. In addition to smaller local exhibitions, it was the site of the 1892 Republican National Convention, the only major party convention to be held in Minnesota until the 2008 Republican National Convention. The idea for an exposition in Minneapolis arose in 1885, when it became known that St. Paul had secured the permanent home of the Minnesota State Fair. Prominent citizens of Minneapolis such as Minneapolis Tribune owner Alden Blethen felt slighted, and an open meeting was called to gauge public support for an annual Minneapolis industrial fair, or exposition, to rival St. Paul's agricultural one. Supporters raised funds throughout the fall of 1885 and reached their goal of $250,000 on December 15. The structure was built on the site of the Winslow House Hotel (today the area bounded by Bank Street SE, Central Avenue SE, Main Street SE, and Ortman Street SE). Designed by Isaac Hodgson, the building had eight stories. Its modified Renaissance exterior was dominated by a 240-foot corner tower. The exterior walls were masonry and the interior had metal support structures. The building's capacity was estimated at between 11,000 and 15,000.The entire building was completed in just over three months: the cornerstone was laid on April 29, 1886, and the building was finished on August 3. On August 23 there was a grand celebration for the opening of the new building and its first exposition. 50,000 people were estimated to have attended and much of downtown was turned over to the celebration. Local dignitaries such as Senator Cushman K. Davis and Archbishop John Ireland spoke at the dedication. US President Grover Cleveland and his wife Frances could not attend. However, they sent a congratulatory telegram that was read publicly, and then in a dramatic moment, Mrs. Cleveland touched a special button in her New York location that started all of the machinery in the building.The initial 40-day exposition was very successful, attracting nearly 500,000 visitors. The latest technology and industrial developments were on display, along with a collection of art and sculpture estimated at $500,000 in value. But in the following years, excitement lessened and the exposition began to lose money. Minneapolis could not have attracted the Republican National Convention of 1892 without the Industrial Exposition Building, but the convention was not enough to halt the exposition's decline. By 1893, exhibitors had evaporated and the fair had fallen apart. In 1896, Thomas B. Janney bought the building at public auction for $25,000, a fraction of what it cost to build. For the next seven years, the space was used sporadically as a performance venue. It hosted the first concerts of the Minneapolis Symphony Orchestra which later became the Minnesota Orchestra and welcomed famous musicians and performers including Johann Strauss and New York's Metropolitan Opera. In 1903, Marion Savage, owner of race horse Dan Patch, bought the building and turned it into the International Stock Food Company. By the 1930s, it was used as a merchandise warehouse for the M.W. Savage Co. mail order company. The structure was finally torn down in 1940 for the construction of a Coca-Cola bottling plant. The bottling plant was torn down in the 1980s and the site has since been redeveloped into condominiums.

The Guthrie Theater, founded in 1963, is a center for theater performance, production, education, and professional training in Minneapolis, Minnesota. The concept of the theater was born in 1959 in a series of discussions between Sir Tyrone Guthrie, Oliver Rea and Peter Zeisler. Disenchanted with Broadway, they intended to form a theater with a resident acting company, to perform classic plays in rotating repertory, while maintaining the highest professional standards. The Guthrie Theater has performed in two main-stage facilities. The first building was designed by Ralph Rapson, included a 1,441-seat thrust stage designed by Tanya Moiseiwitsch, and was operated from 1963–2006. After closing its 2005–2006 season, the theater moved to its current facility designed by Jean Nouvel. In 1982, the theater won the Regional Theatre Tony Award.

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.

Saint Anthony Falls, or the Falls of Saint Anthony (Dakota: Owámniyomni, lit. 'Three Whirlpools') located at the northeastern edge of downtown Minneapolis, Minnesota, is the only natural major waterfall on the Mississippi River. Throughout the mid-to-late 1800’s, various dams were built atop the east and west faces of the falls to support the milling industry that spurred the growth of the city of Minneapolis. In 1880, the central face of the falls was reinforced with a sloping timber apron to stop the upstream erosion of the falls. In the 1950s, the apron was rebuilt with concrete, which makes up the most visible portion of the falls today. A series of locks were constructed in the 1950s and 1960s to extend navigation to points upstream.The falls were renamed from their Dakota title in 1680 by Father Louis Hennepin after his patron saint, St. Anthony of Padua. The towns of St. Anthony and Minneapolis, which had developed on the east and west sides of the falls, respectively, merged in 1872 to fully use the power of the falls for milling operations. From 1880 to about 1930, Minneapolis was known as the "Flour Milling Capital of the World". Today, the falls are defined by the spillway, the upper dam and the locks, located just downstream of the 3rd Avenue Bridge, and the Lower Lock and Dam, just upstream of the I-35W Saint Anthony Falls Bridge. These locks were built as part of the Upper Mississippi River 9-Foot Navigation Project. The area around the falls is designated the St. Anthony Falls Historic District and features a 1.8-mile (2.9 km) self-guided walking trail with signs explaining the area's past.
