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.

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

The Museum is located in the historic State Capital Publishing Company building constructed in 1902. This building was the fourth home of the State Capital Company which was organized in 1889 just prior to the first Oklahoma Land Run. Inside the museum is a large collection of original furnishings and printing equipment. Museum exhibits include the history of the State Capital Company, printing technology and other aspects of life from the territorial and early statehood era.

The museum offers exhibits, tours, demonstrations, workshops, and educational and recreational programs.
