Millions of people have been to visit since the museum opened in 1992, including some famous faces, such as Take That’s Mark Owen - who opened the museum’s Sound Space; Angelina Ballerina - who performed in the Eureka! Town Square; Mister Maker; Maddie Moate and CBBC’s Dick and Dom.
It has won its fair share of awards over the years, such as Visitor Attraction of the Year by the English Tourism Board, the UK’s number one Hands-On Museum by The Independent, and the Gold Award for accessibility at the Visit England Awards for Excellence.
