About us
Under Construction
The Children’s Museum of Rock County is officially under construction, and we couldn’t be more excited! What started as a bold community vision is now becoming a brick-and-mortar reality: a space designed for children to PLAY, learn, grow, and transform.
A Place Built For Kids
The museum will feature hands-on exhibits, immersive environments, and opportunities for open-ended exploration. Whether it’s innovating in the Inventor’s Lab, exploring in the Great Outside Early Childhood Gallery, going to new heights on the Continuum Climb, or connecting with Rock County’s agricultural roots in the Precision Ag experience, every exhibit is built to spark imagination and learning through play.
Why We're Building This Museum
Our children are the future of Rock County. But until now, families had to travel far to find a dedicated children’s museum experience. We’re changing that.
We’re building a place where:
- Kids learn by doing
- Families connect across generations
- Creativity, curiosity, and confidence grow
This museum is for every child in our community, and the ones who come to visit us!
Coming Soon
Construction began in June 2025 and is currently underway at our future home in the former First National Bank at 100 W. Milwaukee Street, Janesville, WI. We hope to open doors and welcome you in late 2026.
Let’s PLAY Together!
