About us

The Museum

The National Museum of Computing is dedicated to showing the development of computing in its broadest sense from the pioneering war time efforts that resulted in Colossus, to the products and systems we use today. The museum is part of the whole Bletchley Park experience, and all visitors to the park can visit the museum free of charge when it is open.

The museum houses the Colossus computer, an exhibition of the most complex code cracking activities performed at the Park, and enhances the Park visitors' experience by continuing the history of the development of computing from the 1940s to the present day.

Our relationship with Bletchley Park Trust

The museum trust is a registered charity and is run independently from, and is not part of, the Bletchley Park Trust. We are responsible for our own fund raising and management which includes funding the lease of H block from Bletchley Park,  where the museum is housed. We work closely with the BP Trust to ensure we offer a comprehensive and seamless visitor experience.
