The Colonel Benjamin Stephenson House is a landmark that links the early history of Edwardsville to the earliest days of the Illinois Territory circa 1809 and the establishment of Edwardsville as the center of government and commerce. It is a connection between Territorial Governer Ninian Edwards, Colonel Benjamin Stephenson, and the State of Illinois. Built in 1820, this two-story brick home, constructed in the Federal style, is an excellent example of architecture from this early period. Each of the four rooms has original millwork; and two of the original mantels designed in the Adams style remain. The home was built with native material by skilled local craftsmen.

The house offers tours, educational programs, other workshops and classes, demonstrations, and occasional educational and recreational events.

Darnall's Chance House Museum is dedicated to the interpretation and study of the history and culture of 18th-century Prince George's County, MD, with special emphasis on the lives of mid-18th-century women. The Museum interprets the story of the widow Lettice Wardrop Thomson Sim, who lived at Darnall's Chance in the decades just prior to the American Revolution. The house and grounds reflect 1760, the year Lettice Wardrop's first husband died and a room by room inventory was taken of the contents of the house. Darnall's Chance also strives to accurately reflect the African-American community on the site and town life in mid-18th-century Upper Marlboro, MD.

In August 1908, Colonel Allen Allensworth and four other settlers established a town founded, financed, and governed by African Americans. Their dream of developing an abundant and thriving community stemmed directly from a strong belief in programs that allowed blacks to help themselves create better lives. By 1910, Allensworth’s success was the focus of many national newspaper articles praising the town and its inhabitants. Today a collection of restored and reconstructed early 20th-century buildings—including the Colonel's house, historic schoolhouse, Baptist church, and library—once again dots this flat farm country.

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