The Chatillon-DeMenil Mansion is a Late Greek Revival historic house museum in St. Louis, Missouri, dedicated to preserving the stories of the founding families of St. Louis and Carondelet. The property documents a remarkable range of histories: a nationally recognized Western explorer, relatives connected to an Oglala Sioux leader, the founder of St. Louis's first drugstore chain, and a literary scholar who helped direct the 1904 World's Fair. Underground caves beneath the grounds carry their own distinct historical narrative. The mansion survived threatened demolition for a highway through dedicated restoration, and now stands as one of the city's recognized examples of Greek Revival architecture. For private events, the mansion opens its historic Carriage House with kitchenette access and its surrounding outdoor grounds to groups of up to 100 guests. Indoor seated dining accommodates up to 60, with the outdoor patio hosting an additional 50. Rental packages include tables, chairs, and tablecloths, with five- and eight-hour options available.

City Museum occupies a former shoe factory in downtown St. Louis, transformed by internationally acclaimed sculptors Bob and Gail Cassilly into an artist-built playground and event destination unlike any other. The building's industrial bones have been reshaped with salvaged architectural elements, mosaic floors, giant sculptural installations, and a 10-story slide that winds through its interior and exterior — all assembled from the materials cities leave behind. For private events, the museum offers five distinct rental spaces accommodating groups from 25 to 4,000 guests. Each venue carries its own character: the oceanic murals and aquarium of the First Floor & Mezzanine, the double vault doors and mirror hallway of the Vault Room, the salvaged facades and hardwood dance floor of Architecture Hall, a historic frontier log cabin beneath MonstroCity, and a 10th-floor corner meeting room with citywide views. Museum admission is included for guests on the day of the event, and the team works with both in-house catering and outside caterers.
