More than just a historical site.

The historic Chatillon-DeMenil Mansion is the place to get a firsthand experience of St. Louis’ French heritage. The museum was once home to famed western guide and hunter Henri Chatillon. Chatillon and his second wife Odile constructed the original section of the house in 1849 at the top of Arsenal Hill to command a view of the Mississippi River.

In 1863 the DeMenil family completed a magnificent addition which turned the Chatillons’ modest home into a Greek Revival mansion. Dr. Nicolas N. DeMenil and his wife Emilie Sophie Chouteau (the great-grand-daughter of Mme. Chouteau and Pierre Laclede) lived here with their son Alexander. The extended family occupied the house until Alexander’s death in 1928.

Weddings and private events have been part of our history at DeMenil since the creation of the Chatillon DeMenil House Foundation in 1964.

The Chatillon-DeMenil Mansion host several special historical tours, educational events and fundraisers throughout the year. All proceeds from our functions and events fund operations and restoration projects throughout the year. Through donations the Mansion can continue to serve as a center for education focusing on the French Heritage of St. Louis.

The Chatillon DeMenil House is a magnificent example of the late Greek Revival style in St. Louis, but its significance is more than architectural.


The house embodies the stories of the families who lived here, including members of the founding families of St. Louis and Carondelet, a nationally known Western trailblazer, the family of an Oglala leader, the first chain drugstore operator in St. Louis, and a literary scholar who was a director of the 1904 World’s Fair. We also tell the story of the caves underneath the property, the highway system that almost destroyed the house, and the preservation efforts that saved it.  We are open for tours four days a week and private events are available on the grounds, in our Carriage House and in the Mansion itself.
