Quick Facts
State: Missouri. Type: privately owned, artist-built museum and playground in the Washington Avenue Loft District of downtown St. Louis. Address: 750 North 16th Street, St. Louis, MO 63103. Founded by artist Bob Cassilly (with Gail Cassilly) in a former International Shoe Company factory/warehouse purchased in 1993. Opened to the public October 25, 1997. Acquired by Premier Parks LLC in January 2019 after Cassilly's death in 2011.
About This Destination
City Museum occupies a former International Shoe Company factory and warehouse in downtown St. Louis's Washington Avenue Loft District, transformed by artist Bob Cassilly and his then-wife Gail Cassilly into a sprawling, hand-built playground of reclaimed materials. Cassilly purchased the mostly vacant building in 1993 and worked on it largely out of public view until visitors began seeing the work-in-progress on New Year's Eve 1996; the museum officially opened on October 25, 1997. What began as a modest attraction grew quickly, drawing 300,000 visitors a year within its first two years and more than 700,000 annually by 2010. Cassilly remained artistic director until his death in 2011, after which the museum continued to expand under his successors until it was sold to Oklahoma City-based Premier Parks LLC in January 2019. The result is less a conventional museum than an indoor-outdoor-underground climbing structure built from salvaged industrial parts, aircraft fuselages, a life-size whale sculpture, and hand-sculpted cave tunnels, spread across multiple floors, a rooftop, and a basement level.
Location
City Museum is located at 750 North 16th Street in the Washington Avenue Loft District of downtown St. Louis, Missouri.
Climate & Weather
St. Louis has a humid continental climate with hot, humid summers and cold winters. Because City Museum's core attractions span indoor, outdoor, and rooftop spaces, weather affects which parts of the experience (rooftop Ferris wheel and slides, for example) are most comfortable to use; specific seasonal averages were not confirmed from a fetched official source for this draft.
Best Time to Visit
Spring and fall offer milder weather for the rooftop attractions, while summer and winter push more of the experience toward the extensive indoor and underground spaces. Weekday visits and non-peak hours are generally less crowded than weekends, given the museum's popularity as a family and group destination; specific crowd-pattern data was not confirmed from a fetched source.
History & Background
Artist Bob Cassilly and his then-wife Gail Cassilly bought the vacant former International Shoe Company factory and warehouse building in 1993 and began an unconventional renovation, building slides, tunnels, and climbing structures from salvaged industrial materials. The project was largely hidden from public view until visitors caught sight of the work-in-progress on New Year's Eve 1996, and the museum formally opened on October 25, 1997. Attendance grew quickly, from 300,000 annual visitors within its first two years to more than 700,000 by 2010. Major additions followed the initial opening, including MonstroCity in 2002 and the Enchanted Caves and Shoe Shaft slides in 2003. Cassilly served as artistic director until his death in 2011. The World Aquarium, which had occupied part of the museum, closed in 2015. In January 2019, American Milling sold the museum to Premier Parks LLC, based in Oklahoma City.
Things to Do
Visitors climb, slide, and crawl through multi-story structures spanning the building's indoor floors, an outdoor MonstroCity climbing complex, an underground cave system, and a rooftop area. The 3rd floor's Skateless Park and Everyday Circus (with daily performances) add scheduled entertainment, while Toddler Town offers age-appropriate play for younger children. The rooftop includes a small Ferris wheel (installed 2006), a ramp slide, a school bus cantilevered over the building's edge, and a 24-foot metal praying mantis sculpture. The museum also hosts themed evening and adult-oriented events such as Glow City and 21+ "City Nights: Underground" programming.
Things to Visit / Highlights
MonstroCity, the outdoor climbing structure added in 2002, includes suspended aircraft fuselages, a fire engine, a castle turret, and connected climbing elements. The Enchanted Caves, added in 2003, are hand-sculpted cave-like tunnels. Indoor highlights include a life-size bowhead whale sculpture, the Vault Room with 3,000-pound bank vault doors, the Shoelace Factory nodding to the building's shoe-warehouse past, and a working 1/8-scale Alco Train. The Cabin Inn, an early-19th-century log cabin with a reported connection to Daniel Boone's family, now operates as a bar beneath MonstroCity.

Safety Tips
The museum's climbing structures, tunnels, and slides involve physical activity at height and in tight spaces, and are not uniformly supervised the way a playground might be; caregivers should supervise children closely, especially on rooftop and MonstroCity elements. Closed-toe shoes are advisable given the metal and reclaimed-material surfaces throughout the structures. For any emergency, dial 911.
Things to Carry
Comfortable closed-toe shoes and clothing suited to crawling, climbing, and sliding are recommended, since much of the museum involves physical activity through tunnels and structures. A change of clothes can be useful given the dusty, industrial nature of some spaces, and a camera for the whale sculpture, MonstroCity, and rooftop views.
Travel Tips & Suggestions
Because the museum spans multiple floors, an outdoor structure, underground caves, and a rooftop, plan for several hours and comfortable footwear rather than trying to see everything quickly. Checking citymuseum.org for the specific day's hours is worthwhile, since hours vary and special ticketed events can affect access. Families with very young children may want to prioritize Toddler Town alongside the more physically demanding climbing areas.
Help Line / Emergency Contact
Dial 911 for any emergency. The museum's general phone number, per its official site, is 314-231-2489.
