The Treasures Gallery, officially the Cadogan Gallery, sits at the top of the grand staircase above Hintze Hall. It holds 22 hand-picked objects that span 4.6 billion years of Earth's history, chosen for scientific, historical and cultural weight. The Natural History Museum lists the gallery on its website with a dedicated audio guide page, but there is no standalone SoundCloud playlist for Treasures in the same format as the Hintze Hall or Evolution Garden guides. In practice that means the official audio coverage for this room is lighter than visitors often expect, and a self-directed listening plan is the best way to do it justice.
This guide lists the 22 objects, flags which ones have recorded commentary available from the Museum or partner sources, and suggests a short order for anyone with 30 minutes and a pair of headphones.
The gallery at a glance
The Cadogan Gallery reopened in November 2012 after a careful restoration. The design firm Casson Mann placed the objects on plinths down the centre of the room, lit softly through stained glass. Critics at the time described the effect as ecclesiastical, closer to the treasury of a provincial cathedral than a typical museum hall. Identical touchscreens at each artefact deliver deep contextual information without cluttering the sight lines. The ceiling carries a custom tree artwork commissioned for Charles Darwin's 200th birthday in 2009. Typical dwell time is 20 to 40 minutes.
The gallery was conceived as an antidote to the Museum's usual overwhelming scale. Instead of thousands of specimens, visitors focus intensely on a curated few.
Is there an official Treasures audio guide?
The Natural History Museum maintains a page at nhm.ac.uk/visit/galleries-and-museum-map/treasures/audio-guide that hosts embedded audio. Unlike Hintze Hall, which has a clearly tracked 24-stop SoundCloud playlist narrated in part by David Attenborough, the Treasures audio is not organised as a publicly indexed playlist. You will find stronger recorded commentary on a handful of these objects through the Museum's wider content: the emperor penguin egg, Archaeopteryx and the Apollo Moon rock all appear in podcasts, short films and curator talks on the NHM's YouTube channel and the Museum's own articles.
If you want continuous recorded audio while walking the room, the realistic options are:
- Open the Museum's Treasures audio guide page on your phone before you enter, since Wi-Fi in the gallery can be patchy.
- Queue up specific object podcasts from the NHM's back catalogue for the objects listed below.
- Read the touchscreen content at each object, which is the deepest source and was designed to be the primary interpretive layer.

The 22 Treasures
The full list, cross-referenced from the Museums Association review, the NHM's own highlights page and independent visitor guides.
- First edition of On the Origin of Species (1859). The Museum library holds 478 editions in 38 languages and Braille.
- Archaeopteryx, the earliest known bird and, in the Museum's own words, the most valuable fossil in its collection.
- Dodo subfossil remains. Bones more than a thousand years old, from a bird extinct by the late 1600s.
- Great Auk specimen collected on Papa Westray, Orkney, in 1813. The species was extinct by 1844.
- Moa, the extinct flightless bird of New Zealand.
- Darwin's pigeons, the specimens he used to work out artificial selection.
- Emperor penguin egg collected on Robert Falcon Scott's 1911 Antarctic expedition, the journey Apsley Cherry-Garrard called the worst in the world.
- A plate from Audubon's Birds of America, the original double-elephant folio.
- Neanderthal skull.
- Barbary lion skull found in the moat of the Tower of London in 1937, roughly 700 years old.
- Ammonites, the iconic spiral fossils.
- A meteorite billions of years old.
- Apollo Moon rock, the only piece in UK ownership, a gift from President Nixon after the final crewed Apollo mission.
- Iguanodon teeth discovered by Mary Ann Mantell, the find that started the scientific study of dinosaurs.
- Dwarf elephant teeth from extinct insular species.
- Hans Sloane's carved nautilus shell. Sloane founded the British Museum.
- Blaschka glass models of marine invertebrates, made by Leopold and Rudolph Blaschka between 1876 and 1889.
- A second set of Blaschka glass models.
- Joseph Banks herbarium sheets from Cook's Endeavour voyage.
- George Clifford herbarium sheets, linked to Linnaeus's Hortus Cliffortianus.
- Alfred Russel Wallace's insects, collected by the co-discoverer of natural selection.
- Portrait of Richard Owen, the first superintendent of the Museum and the man who coined the word dinosaur.
At the right-hand entrance stands Guy the Gorilla, the taxidermy specimen of the much-loved former resident of London Zoo. Guy is not one of the 22, more a guardian of the room.
What to listen to first: a 30-minute order
If you only have half an hour and want the richest audio experience, work through the objects in this order.
- Archaeopteryx. Start here. The first specimen ever found is the single object in the room with the strongest combination of scientific importance and curator-recorded commentary. Touchscreen plus any queued NHM podcast on early birds.
- Emperor penguin egg. The Scott expedition story is one of the most vivid in British exploration history. The touchscreen covers the science; the Museum's short films fill in the human cost.
- First edition of On the Origin of Species. The book that reorganised biology, sitting a short walk from Darwin's pigeons. Read the two together.
- Apollo Moon rock. The only Apollo sample in UK hands. Brief but worth it for the Cold War provenance alone.
- Dodo remains. Extinction as a concept was debated into the 19th century. Standing in front of real dodo bone is a short course in why it matters.
With time left over, the Blaschka glass models reward quiet attention. Nothing on audio really captures them; they are a looking object, not a listening one.
How the Cadogan fits into a visit
The Treasures Gallery sits off the first-floor balcony above Hintze Hall. Most visitors arrive after finishing the main hall below and before moving into the Red Zone or the Blue Zone dinosaur route. Thirty minutes is a reasonable allocation. An hour if you read every touchscreen. For overall pacing across the Museum, see the piece on [how long a Natural History Museum visit takes]how long does nhm take.
Accessibility notes
The gallery is step-free from the lift on the first floor. Touchscreens sit at a height usable from a wheelchair. Audio-described tours of the Museum's headline galleries are produced in partnership with VocalEyes, though coverage of Treasures within that programme is limited. Visitors who rely on described audio should contact the Museum's access team in advance.
FAQs
Is there an official audio guide for the Treasures Gallery?
The Museum hosts a Treasures audio guide page on its website, but it is not released as a public SoundCloud playlist in the way that Hintze Hall is. Coverage is object-by-object rather than a single continuous tour.
Which Treasure has the best audio coverage?
Archaeopteryx. The specimen is central to the Museum's scientific identity, and it appears in more curator talks and podcasts than any other single object in the Cadogan.
Can I use the Treasures audio without Museum Wi-Fi?
Load the audio guide page on your phone before entering the gallery. Signal inside the Cadogan is inconsistent.
How long should I spend in the Treasures Gallery?
Twenty to forty minutes covers the room comfortably. An hour is reasonable if you want to read every touchscreen in full.
Is Guy the Gorilla part of the 22 Treasures?
No. Guy stands at the entrance as a guardian to the gallery, not as one of the curated 22 objects.
About the author. Hendrik Schafer is the founder of Musa, an AI audio guide platform used by museums across Europe and North America. He writes about how visitors actually move through collections and where official audio coverage helps or falls short.
Try a different way to hear the Cadogan. If the Museum's own audio feels thin in this room, Musa's self-guided audio tours let you listen to each Treasure at your own pace, with context that picks up where the touchscreens leave off. Worth a look before your next visit.
