Located in Collinsville, Illinois, this historic area is the site of the largest pre-Columbian Native American village north of Mexico. It is a veritable record of pre-modern structures and the implied social organization that resulted. An interpretive center presents an orientation film each hour on the hour.

DOWNTOWN. Built in 1851 in Lucas Place, the city's then-ritziest neighborhood, this three-story townhouse was home to the family of Robert Campbell, an immigrant entrepreneur and one of the state's wealthiest men during his life. Following a $3 million restoration, it has been returned to its high Victorian glory, full of family possessions and artifacts. Replica textiles, original lighting fixtures, authentic furniture, and lots of decorative arts create a scene of century-old opulence, offering a glimpse into St. Louis's early days.

Originally this home served as the four-room brick farmhouse of American Fur Company wilderness guide Henri Chatillon and his wife. Eight years later they sold the house to the DeMenil family who transformed the small home into a Greek Revival mansion. Successive generations of the family lived in the home until 1945. It is now maintained by the Landmarks Association and features original furnishings and the Café DeMenil, which is situated in the mansion's original carriage house.

This farm once belonged to Ulysses S. Grant and was bought by the Busch family almost a hundred years ago. Today, the estate, compliments of Anheuser-Busch, is a wildlife preserve. Travel in an open-air coach past Mirror Lake to Grant's Cabin, constructed by Grant in 1856. Ride past Deer Park and view bison, elk, antelope, zebras, llamas and ostriches. See the famous Clydesdales in their pastures next to the stables. Enjoy entertaining, educational shows at the Tier Garten Amphitheater. You can also visit the petting area and hand-feed the smaller animals.

Enjoy interactive and hands-on exhibits and programming about the Lewis and Clark Expedition and marvel at their amazing journey. Reenactments of the river portion of the journey are undertaken every year, using replicas of the original boats. Be sure to visit the Trading Post museum shop before you leave.
