The St. Peter Armory was the first state-owned armory built in Minnesota. Architecturally, the structure is an excellent example of Minnesota's so-called "early period” armories, all of which predate World War I. The building is also important because it served as a center of military and social affairs in St. Peter.

Constructed in Minneapolis in 1919, the Northeast Neighborhood House (NENH) served both as a portal into American society for newly arrived immigrants from Eastern Europe and as an advocate for the neighborhood's underprivileged. It is a notable example of a social institution created solely for the betterment of the disadvantaged.

Built by the Civilian Conservation Corps (CCC) between 1934 and 1935, the Marcell Ranger Station exemplifies the core principles of the National Park Service's architectural philosophy: minimalist construction and use of native materials.

Built in 1909, the Winona Masonic Temple with its large public ballroom and other meeting rooms was an important center of social and civic activity in the city. It continues to serve Winona in the twenty-first century.

Built in 1929 at Forty-Sixth East Fourth Street, the Minnesota Building represents a turning point in the economic history of downtown St. Paul and the architectural history of the entire Twin Cities area.

Ramsey County's third courthouse, which opened in 1932, is a treasure trove of wood, stone, sculpture, and Art Deco style.

The K. J. Taralseth Company building is a physical reminder of the early commercial development of Warren. After moving from a brick store that was destroyed by fire in 1910, Ralph Taralseth built a new store that reflected the company's success. The new building carried a mixed product line for which the company became known. It also provided space for the professional services and fraternal organizations forming in and around Warren.

In 1868, the grain trade in Minnesota was growing, but few railroads existed in the state. Steamboats were the supreme mode of transportation. William Robinson built a grain warehouse on the banks of the Mississippi to take advantage of the steamboat traffic. Shortly afterward the town of Jefferson was plotted. In a few years, however, the railroad came through, and a larger town was platted to the south. The Jefferson Grain Warehouse quickly became obsolete.

The Father Louis Hennepin Bridge was built in 1855 to take advantage of the transport possibilities provided by the Mississippi River above St. Anthony Falls. It was the first bridge built to span the Mississippi river, and made crossing its length above the Falls much easier. The rushing rapids helped to create industry on the river and spurred a population boom that made Minneapolis the most populated city in Minnesota.

The Czechs who came to Roseau County beginning in the 1890s were some of the first European Americans to homestead on land in northwest Minnesota. Czech fraternal lodges were created in America by immigrants to promote their welfare, maintain cultural traditions, and satisfy social needs. Lodge Boleslav Jablonsky was one such lodge.
