Our collection

The Science Museum Group cares for an astonishingly diverse and internationally significant collection of 7.3 million items from science, technology, engineering, medicine, transport and media.

Together these objects tell the story of our world—from the rise of the Indus Valley civilisation over 3,000 years ago to the microchips powering our connected planet today.

We have embarked on an ambitious project to transform how we care for and share this remarkable collection with the world. This once-in-a-generation project will dramatically improve public access to many thousands of historic items, enabling you to explore more of the collection than ever before.

About the collection

Our collection traces its origin back to the 1851 Great Exhibition. Among the 7.3 million items we now care for there are:

  • 140,000 medical items, including the long-term loan of the Wellcome Collection
  • 38,000 items relating to railway locomotives, technology and railway life
  • 26,000 scientific instruments
  • 17,000 items of photographic, cinematographic and televisual technology
  • 7,000 artworks

Standout items from our collection include: Alan Turing’s Pilot ACE computer; one of the first models used to represent atoms; Charles Babbage’s drawings and models; Dorothy Hodgkin’s model of penicillin; Helen Sharman’s spacesuit and Tim Peake’s spacecraft; Amy Johnson’s Gipsy Moth aircraft; famous locomotives from Stephenson’s Rocket and Sans Pareil to Mallard and Flying Scotsman and the world’s earliest surviving photographic negative.

Accessing the collection at Blythe House

The Science Museum Group has begun an ambitious project to transform how we care for and share our collection with the world.

During the next five years, over 300,000 items currently held at Blythe House in London will be studied, photographed, packed and moved into a new building at the National Collections Centre in Wiltshire.

Due to this extensive programme of work, there will be no public access to the collection held at Blythe House from April 2019. Access to the National Collections Centre is also restricted until 2023.

Many items held at Blythe House are being digitised as part of the project, with hundreds of new images published online each month.

Throughout this period the Science Museum’s Library and Archive, Search Engine at the National Railway Museum, Insight at the National Science and Media Museum and the Collections Centre at the Science and Industry Museum will remain accessible.

Access to information about items collected by the Science Museum can be found by contacting smlinfo@sciencemuseum.ac.uk.

Our ambitious project has created opportunities to review the items we hold, enhance our records and digitise a vast part of the collection for the public and researchers to explore on our collection website.

From 2023, the public, researchers and school groups will be able to explore over 80% of the Science Museum Group Collection in its new home at the National Collections Centre in Wiltshire.

Detailed information on how to join a regular public tour, or visit the National Collections Centre as a researcher or school group will be published closer to the time.

Our collection research facilities at the Science and Industry Museum, National Science and Media Museum, and the National Railway Museum remain open.
