Lincoln Log Cabin preserves the site of the last home and farm of Abraham Lincoln's father and stepmother, Thomas and Sarah Bush Lincoln. The Lincolns moved to the farm in 1837. Featured at the site are two living history farms that portray recreated agricultural practices as they existed in 1840s Illinois—the Thomas Lincoln Farm and the Stephen Sargent Farm. About 10 acres of period crops are cultivated, along with a hay field. Animals include teams of working oxen and horses, several sheep, and hogs similar to the razorbacks with which 1840s Illinois farmers were familiar.

The site offers exhibits, living history demonstrations, a short film, and educational and recreational programs and events.

The Site preserves the central section of the largest prehistoric Native American city north of Mexico. Occupied from 700 to 1400, the city grew to cover 4,000 acres, with a population of between ten and twenty thousand at its peak around 1100. The site is dominated by the 100-foot-tall Monks Mound, the largest prehistoric earthen mound in the Americas. In 1966 Cahokia Mounds was placed on the National Register of Historic Places and in 1983 was designated a World Heritage Site by UNESCO. Cahokia Mounds preserves 68 of the original 120 earthen mounds built by prehistoric Native Americans. Visitors may climb a stairway to the top of Monks Mound, where interpretive signs provide an explanation of the impressive view. Other physical features include a reconstructed stockade wall and "Woodhenge," a circle of posts around a large central post from which the sunrise can be aligned to determine the season and time of year. The Interpretive Center houses museum exhibit galleries, an orientation show theater, a public programming auditorium, staff offices, and a courtyard for educational programs. Exhibit galleries and an award-winning orientation show, "City of the Sun," describe the Native Americans who lived there as well as the site's historic and archaeological significance.

The Dawes House was built in 1894–5 on a two-acre site near Lake Michigan. Designed in the style of French chateaux by architect Henry Edwards-Ficken of New York, the massive three-and-a-half story structure has 25 rooms, six bedrooms, seven bathrooms and 11 fireplaces. The house was built for Robert Sheppard and his family; it was purchased by Charles Gates Dawes in 1909 and remained the Dawes family home until 1957 when it was given to Northwestern University to be used as the headquarters of the Evanston Historical Society (now known as the Evanston History Center). Northwestern University gave the house to the EHC in 2009.

The house is open to the public for docent-led tours. The two parlors, formerly used as a reception room and a music room, now feature exhibitions. The library, dining room, and great hall are furnished mostly with original Dawes pieces. A permanent exhibit on Evanston history is located on the second floor, with smaller rotating exhibits on the 2nd floor and in the research room.

The EHC offers lectures, workshops, and other educational programs, as well as community events. School and group tours are available upon request. The EHC maintains an extensive archives of documents, maps, photographs, films, clipping files and other resources and is open to the public during designated hours.

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.
