The Pommer-Gentner house, built in 1840, is a sterling example of high-style German neoclassicism and is furnished to reflect the earlier settlement period of the 1830s and 1840s. Behind the house, visitors will tour a period garden and a small half-timbered barn containing an exhibit of 19th-century tools. The Strehly house, built in stages from 1842 to 1869, has a traditional German vernacular front. It once contained a full-service printing company that produced a German-language newspaper. About 1857, Carl Strehly built a winery next to the house that today displays one of a few remaining carved wine casks in the Midwest. Grapevines, planted by the Strehlys in the 1850s, can still be seen running the length of the backyard. Deutschheim's varied collections of German Americana are represented by galleries of changing artifacts and photographs.

Missouri's first legislators met in the buildings of the First Missouri State Capitol State Historic Site to undertake the task of reorganizing Missouri's territorial government into a progressive state system. From June 4, 1821, to Oct. 1, 1826, heated debates of state's rights and slavery filled the rooms of the temporary Capitol. The second floor of two adjoining Federal-style brick buildings was divided and used as Senate and House chambers, an office for the governor, and a small committee room. The first floor of the Peck brothers' building housed a general store and Ruluff Peck's family residence. Chauncy Shepard operated a carpenter shop on the first floor of the adjoining building. For a nominal fee, visitors can take a guided tour through the actual restored and furnished rooms where Missouri state government was created and first practiced. The restored Peck brothers' general store and residence have been furnished as they might have looked in the early 1800s. Admission is free to the historic site's interpretive center, which offers two floors of exhibits and an orientation show.

The site offers a short film, exhibits, tours, and occasional recreational and educational events.

A renowned painter, sculptor, lecturer, and writer, Thomas Hart Benton had a gift for interpreting everyday life. One of his most noted murals, "A Social History of the State of Missouri," can be viewed in the House Lounge of the state Capitol. Virtually untouched since his death in 1975, the two-and-a-half story, late Victorian-style house that Benton called home was constructed of native, quarried limestone and contains simple furnishings in neutral tones that contrast Benton's vibrant paintings. Several of Benton's paintings and sculptures can be viewed in the house. Benton converted half of the carriage house into his art studio, which remains as he left it, with coffee cans full of paintbrushes, numerous paints, and a stretched canvas waiting to be transformed into another of his masterpieces.

For over 400 years Ojibwe families of Grand Portage have tapped maples every spring on a ridge located just off Lake Superior. During the summer, Ojibwe fishermen harvest in the same areas their forefathers have. Before the United States and Canada existed, the trading of furs, ideas, and genes between the Ojibwe and French and English fur traders flourished. From 1778 until 1802, welcomed by the Grand Portage Ojibwe, the North West Company located their headquarters and western supply depot here for business and a summer rendezvous. Today, Grand Portage National Monument and Indian Reservation form a bridge between people, time and culture.
