The Grout Museum District is set to open the new Imaginarium Science Gallery on December 15, 2026. The facility will be housed within the existing Grout Museum of History and Science.
Why it matters
The new gallery provides a permanent home for science exhibits following the closure and demolition of the former standalone Imaginarium facility on Washington Street. This integration ensures continued access to interactive science education in the Waterloo area.
The new gallery project is supported by the Reimagine the Imag campaign, which provides funding for the site's renovations and exhibit development. This opening follows the closure of the previous science facility in 2025.
The players

Market Landscape
The Imaginarium expansion follows a broader trend of museum consolidation within the Grout Museum District, which seeks to centralize educational resources. This move positions the organization to offer a more cohesive visitor experience by housing science exhibits alongside historical collections.
Residents in Waterloo and the surrounding Cedar Valley will regain access to interactive science programming in a centralized location. The move consolidates museum offerings, allowing families to visit both historical and scientific exhibits during a single trip to the main campus.

The transition to an integrated museum model reflects a shift toward centralized cultural hubs in the region. Visitors can anticipate updated interactive exhibits that replace those lost following the demolition of the former Washington Street site.
