The Apple River Fort was the site of an important battle during the Black Hawk War. It was the only fort attacked by Black Hawk during the turbulent summer of 1832. On June 24, 1832, the settlers at the fort turned back an attack by some 200 Sauk and Fox warriors led by Black Hawk. The war, which lasted only 16 weeks, ended the threat of Indian attacks in the area and opened the region to further settlement. Many notable men participated in the Black Hawk War including a young Abraham Lincoln, Jefferson Davis, and General Winfield Scott. Abraham Lincoln and his militia company arrived at the fort the day after the battle. Today, the fort has been reconstructed and is open for self-guided tours. Special events throughout the year highlight many aspects of life in Jo Daviess County in 1832. Exhibits at the Interpretive Center, on the trail, and at the fort tell the story of the Sauk and Fox, the early settlers, and the conflict that became known as the Black Hawk War.

The site offers exhibits and occasional recreational and educational events.

The Historic Pullman Foundation supports visitation, preservation, and restoration of the historic town of Pullman, Illinois. Founded in 1880 by George M. Pullman, president of Pullman's Palace Car Company, as a model industrial community, Pullman was situated for easy access to the big city markets of the day via rail. Buildings of note include the 1881 Hotel Florence; the 1880 rail car construction facility; the 1893 Market Hall, and the 1887 Greenstone Church, which contains one of the few manual tracker organs in the U.S. today. Artifacts on view include furniture from the Pullman Mansion and Hotel Florence, as well as a model train collection of Pullman manufactured rail cars.

Historic Pullman offers exhibits, an educational video, self-guided tours, walking tours, and tours specifically for schools and/or large groups.

The Fulkerson Mansion and Farm Museum presents the cattle farm—Hazy Dell—and Southern-style Victorian mansion which became the home of Lt. Colonel William H. Fulkerson after his stint with the Confederate Army. Hazel Dell is virtually unchanged today; and the Farm Museum contains many rare agricultural items and equipment with emphasis on farm steam traction engines—utilized for plowing the prairie, threshing grain, and for powering early sawmills. The museum features Reeves steam engines and plows, while the 1866 mansion is furnished with antiques and artifacts of the period, with a special display of the Fulkerson's personal Civil War items, Lafayette Baker's Civil War artifacts, and the Thomas Lincoln Anvil. The building is in an Italianate style—with a low pitched roof and tall, narrow windows—popular between the 1850s and 1880s.

The site offers exhibits and tours of the mansion.

The Lincoln-Herndon Law Offices are within the only remaining building in which Abraham Lincoln maintained a law office. The site consists of the surviving portion of a three-story brick commercial block constructed in 1840–41. The restored building's first-floor visitor center consists of an exhibit gallery and audiovisual theater, along with a room interpreted as an 1840s post office facility. On the second floor are rooms representing those used by the federal court, and on the third floor a "common room" and three lawyers' offices. Two of the offices were used by Lincoln and his partners, prominent local attorneys Herndon and Stephen T. Logan. The recreated offices are notable for the plainness and disorder that were remembered by Lincoln associates.

The site offers exhibits, a short film, and tours.
