The National Museum of Computing (TNMOC) is home to the world's largest collection of working historic computers.
Follow the development of computing: from the Turing-Welchman Bombe and Colossus of the 1940s through the large systems and mainframes of the 1950s, 60s and 70s, to the rise of personal computing and the rise of mobile computing and the internet.
Recognised as one of England’s top 100 ‘irreplaceable places’, we welcome corporate and group visits, schools and individuals from all over the world.
We have not yet returned to our 6 day opening schedule, we aim to open to the public Tuesday, Thursday, Saturday and Sunday - 10:30am - 4:30/5pm - last entry 3.30/4pm - but please check our Days Open page before planning your visit.
In the future we plan to extend to Tuesday to Sunday 10:30am - 5pm (spring/summer), 10:30am - 4:30pm (Autumn/Winter)
TNMOC operates independently of Bletchley Park Trust, although we are located on the Bletchley Park Estate.

UPCOMING EVENTS
We have a number of very interesting events and Virtual Talks over the next few months, as well as our very popular Guided Tours in the Museum.

Faced with a series of perplexing puzzles and challenges inspired by computing technology across the decades, you must gather your wits, problem-solving and team-working skills to beat the ticking clock in a thrilling race to the finish line to determine your fate. Prepare to be confronted with alien tools and technology from decades past - paper tape, punched cards and floppy disks to name a few. Designed to please even the most discerning Escape Room hobbyist, our Escape Room Challenges boast the added bonus of educating our escapees on the history of Computing along the way!
The decades available to choose from are:
1940s: Would you have made it as a successful code breaker at Bletchley Park during WWII? It’s time to find out! Use an Enigmatix, a single wheel poly-alphabetic encryption system which mimics a rotor from the original Enigma machine, to decrypt puzzles and tackle cryptography 1940’s style.
1950s: Wrap your head around a cryptic crossword and take on the challenge of binary addition to reveal a top secret code.
1960s: Get your mathematics brain in gear and read data from punched cards.
1980s: Write a program on a retro BBC Micro.
Vouchers are priced at a rate of £32.00 per person, discounted to £57.00 for a pair. Vouchers are valid for 12 months from the date of purchase. Full Museum admission is included in the ticket price, allowing you to explore and be inspired by our extraordinary collection whilst you are here. The experience will last for 90 minutes. This includes a 15 minute 'Mission Briefing' followed by 75 minutes to complete the Escape Room Challenge.
We look to run these on a Saturday Morning, Tuesday evening and Sunday afternoons. Once you have purchased your package you will receive confirmation and details of how to book. For Team Events and larger groups contact Jacqui.Garrad@tnmoc.org
