The house built in the 1880s by Henry G. Leathers on a site near the Rum River is a prime example of late-Victorian architecture in Anoka County. Used as both a dry goods store and a family home, the building is dually significant—first for its level of preservation and second for its association with a family that contributed to the commercial, social, and religious history of the town of St. Francis for three generations.

Originally built in the 1870s at 214 Jackson Street in Anoka, the Jackson Hotel was destroyed in an 1884 fire. It was quickly rebuilt and continued to function as a hotel until 1975, making it a center of local commerce and social gatherings for more than ninety years.

Designed by noted architect Frederick Marsh, this seventeen-room Georgian Revival-style home, built in Anoka in 1904, received the name “Colonial Hall” courtesy of its original residents, the doctors Alanson and Flora Aldrich.

Bemidji’s Great Northern Depot—James J. Hill’s last commissioned depot—celebrated its grand opening in January of 1913. Replacing the first Great Northern Depot, a wooden structure built in 1898, this impressive brick and sandstone building provided space and modern amenities to accommodate the needs of the growing community.

In 1895, the Polish immigrant community in Winona raised funds to construct St. Stanislaus Kostka, the grand church dominating the city’s skyline. The church, which still serves the East End parish, was listed on the National Register in 1984 and elevated to a minor basilica of the Catholic Church in 2011.

Crescent Grange Hall #512 in Linwood Township is an artifact of Reconstruction-era Minnesota (1865–1877). During this period, rural residents united in response to economic upheaval and high interest rates. Farmers, particularly those in the south and west of the state, struggled to make a living in a volatile and unregulated economy.

The Pine River Dam and Power Plant was built in 1911 and provided power until 1946, when it was converted into a recreational area.

Huset School, an example of the kind of one-room log schools once common in northern Minnesota, was built in Boy Lake Township (Cass County) in 1912. Cass County Historical Society restored it in 1968 and opened it to the public as a historic site.

The sixth and final dam in the Headwaters Reservoir System, Gull Lake Dam was built in 1912 to increase the output of mills and turbines downstream. In 2019, the dam maintains water levels for recreation and navigation, and the site is also home to ancient burial mounds and a recreation area.

The Ranier Railroad Bridge (Canadian National River Bridge) was constructed in 1908 by the Canadian Northern Railway and its subsidiary, the Duluth, Rainy Lake and Winnipeg Railway. The single-track lift bridge crosses Rainy River between Ranier, Minnesota, and Fort Frances, Ontario, and is one of the busiest ports of entry for international rail freight in the United States.
