The National Museum of Computing (TNMOC) is home to the world's largest collection of working historic computers.
Recognised as one of England’s top 100 ‘irreplaceable places’, follow the development of computing from the ultra-secret pioneering efforts of the 1940s, through the large systems and mainframes of the 1950s-70s, to the rise of personal computing in the 1980s and beyond.
We aim to open to the public Tuesday, Thursday, Saturday and Sunday - 10:30am - 16:30pm during Winter hours (extended to 17:00pm during Summer hours) - but please check our Days Open page before planning your visit.
We recommend you BOOK ONLINE in advance of your visit (booking fee will apply) but we also welcome visitors on the day.
Why not plan a visit to our world leading computing museum? We offer individual, family, and annual tickets and we are easy to reach by public transport or car.
Whether you are a business organisation or a private group of friends, we tailor your group visit to fit your requirements, and you will benefit from the knowledge of our highly experienced, friendly tour guides.
Computable90 - Academic Engagement & Conference
Celebrating Alan Turing’s first and foremost idea
In 1936, Alan Turing’s seminal paper ‘On computable numbers, with an application to the Entscheidungsproblem’ was published by the London Mathematical Society. Ninety years on, the significance of the work done by Turing remains undiminished. It occupies a unique position of ongoing relevance in the fields of symbolic logic, number theory, problem complexity, computer science and more. In wider social terms, its impact on the development of computing is without parallel.
The National Museum of Computing and the London Mathematical Society are honoured to be able to facilitate a major international conference on the ideas and influences prompted by Alan Turing’s ground-breaking 1936 paper published in the Proceedings of the LMS. The world’s leading research mathematicians, philosophers and thinkers – all working in fields which have arisen from the original ‘Computable Numbers’ idea back in 1936 – will present their work and explain how ideas imagined 90 years ago have relevance today.

BLETCHLEY, UK – 17th June 2026 – The National Museum of Computing (TNMoC), located on the Bletchley Park estate, is proud to announce that IEEE, a public charity and the world’s largest technical professional organization advancing technology for the benefit of humanity, has officially approved the designation of the Colossus Computers (1944-1945) as an IEEE Milestone.
The IEEE Milestone Program recognises Colossus as one of the most significant technical achievements in computer history. The Milestone plaque will be officially unveiled during a landmark dedication ceremony at the Museum on Tuesday, 29 September 2026, held in conjunction with the 2026 Tony Sale Award for Computer Conservation.
The National Museum of Computing (TNMOC), in partnership with the London Mathematical Society (LMS), has announced a landmark three-day international conference: Computable 90.
Taking place from 16–18 September 2026 within the Fellowship Auditorium at the historic Bletchley Park, this summit marks 90 years since Alan Turing’s 1936 paper “On Computable Numbers” changed the course of human history. The event will bring together the world’s most influential mathematicians, philosophers, and computer scientists to discuss how Turing’s original logic continues to define the technological landscape of the 21st century.
The National Museum of Computing (TNMOC), has today announced that Simon Lavington, M.Sc., Ph.D., FIEE, FBCS, C.Eng - an Emeritus Professor in the Department of Computing and Electronic Systems at the University of Essex - is to be awarded an Honorary Fellowship of the Museum. The Honorary Fellowship recognises outstanding contributions towards the history and ongoing development of computing.
The National Museum of Computing partners with LogRhythm to preserve technological heritage and promote inclusion in the cybersecurity industry. LogRhythm is sponsoring TNMoC to bolster engagement in computing and recently held its Customer Advisory Council and Partner Advisory Council at the Museum as part of the ongoing collaboration.
The National Museum of Computing (TNMoC) is thrilled to announce a major funding partnership with The Post Office Remembrance Fellowship (PORF). This funding paves the way for a significant milestone in TNMoC's evolution as it embarks on a major building refurbishment project to preserve an irreplaceable World War Two-era building.
The Computer Conservation Society (CCS) is thrilled to announce the revival of the prestigious international Tony Sale Award, honouring exceptional achievements in the realm of computer conservation and restoration. Named in memory of the visionary computer conservationist Tony Sale, the award was instituted in 2012 to acknowledge outstanding contributions in the field of computer preservation and restoration.
We are thrilled to share the fantastic news that the National Museum of Computing has been honoured with full Accreditation as a Nationally Styled Museum through the UK Museum Accreditation Scheme.
Receiving full accreditation as a nationally styled museum recognises our collections’ national importance and international interest, our support of other museums working in our field, our learning programme, and our ongoing research and scholarly publications.
