From humble beginnings to five floors of indoor fun and a 7.5 acre outdoor sports wonderland, our story has grown over the past 100 years. Take a look back at some milestone moments from our first 100 years.

1925

On Dec. 5, Mary Stewart Carey and four others founded The Children's Museum in a carriage house at the Propylaeum.

After a stint in Garfield Park, the museum moves to Mrs. Carey's home—but quickly runs out of room. The museum then acquires the Parry house at 30th and Meridian streets in an auction.

Crowds line Meridian Street to watch the Reuben Wells, perched upon a flatbed truck, make its way to the museum from Altoona, Pennsylvania.

1973

Ground breaks on a new, dedicated museum building at 30th and Meridian Street. At 225,000 square feet, it will be the largest children's museum in the world—a distinction still held today, though the building is now 482,950 square feet.

First Lady Betty Ford visited The Children's Museum and was one of the first people to ride the newly-installed Carousel.

Mascot Rex is introduced—with a look perhaps better suited for the Haunted House. His original mask is now part of the museum's permanent collection.
