London is a city of world-class museums - the British Museum, the V&A, the Natural History Museum. All are outstanding, all are free and all are famous.
But if you want to find something a little bit different; something eccentric, surprising, and genuinely unlike anything else the capital has to offer, then get yourself down to Forest Hill.
Because tucked away in a leafy corner of south-east London, the Horniman Museum and Gardens has been quietly wowing visitors for well over a century, even though most Londoners have never even heard of it!
The Man Behind the Museum
To understand the Horniman, you first need to understand Frederick John Horniman. A Victorian tea trader of some wealth and even more curiosity, he spent decades travelling the world - Egypt, Sri Lanka, Burma, China, Japan, Canada - collecting objects, artefacts, and specimens wherever he went. His stated mission was to "bring the world to Forest Hill" and educate his local community. Which was, when you think about it, a wonderful thing to want to do.
By the late 19th century, his collection had grown so large that his own house could no longer hold it! So in 1901, he commissioned the architect Charles Harrison Townsend to design a purpose-built museum, and then - in an act of extraordinary generosity - handed the whole lot over to the people of London, free of charge.
The building itself is a beauty. A striking ‘arts and crafts’ structure (emphasising simplicity and using local materials) in honey-coloured stone, it sits on the brow of a hill. Across the top of the facade there is an ornate mosaic, leaving you to think this looks like somewhere important things happen. Well, they do.
What's Inside
Today the Horniman is home to over 350,000 objects. Yes - that many. The collections span anthropology, natural history, and musical instruments, and together they add up to one of the most eclectic and genuinely thrilling museum experiences in the country.
The Anthropology collection is, arguably, the heart of the place. More than 80,000 artefacts from across the globe - masks, textiles, ritual objects, and everyday items from Africa, Asia, the Americas, and the Pacific - fill the galleries in a way that is both thoughtful and fascinating.
Look out for the Benin Bronzes: extraordinary brass plaques looted from Benin City by the British army in 1897. In 2022, following a request from the Nigerian government, the Horniman became one of the first UK museums to agree to return ownership of these objects - a decision that drew widespread praise and placed the museum at the forefront of an overdue national conversation. Some pieces remain on loan and can still be seen in the gallery, but their status is a reminder that museums are living institutions, not just storage facilities for the past.
Musical Instruments Gallery
Downstairs, the Musical Instruments Gallery is an absolute treat. With over 3,000 instruments from virtually every corner of the world, it is one of the most comprehensive collections of its kind in the UK. In a single visit you can travel acoustically from an Uzbek wedding to a West Cameroon funeral, from a Tibetan Buddhist ceremony to the Rio Carnival.
There are listening posts where you can hear instruments being played, and interactive tablets for younger visitors. The collection also includes the archive of Boosey & Hawkes, once Britain's largest instrument maker - at their peak in the 1960s, their London factory was producing over a thousand instruments a week.
The Walrus
And then there is the walrus.
Currently being refurbished and due to return when the Natural History Gallery reopens in early 2027, this magnificent creature has been the museum's unofficial mascot for over a hundred years. Victorian taxidermists, having never actually seen a living walrus, simply stuffed the skin until it was full. The result is an animal that is comically over-inflated, like a walrus that has eaten several other walruses.
It is rather absurd and completely marvellous, and its imminent return to the gallery is genuinely one of south London's most anticipated cultural events.
The Gardens
Step outside and the surprises keep coming. The Horniman Gardens cover sixteen acres and offer some of the most spectacular views across London you'll find anywhere - a sweeping panorama stretching from the City to Canary Wharf, best enjoyed from the upper terraces on a clear day with a coffee from the on-site café.
The gardens themselves are a horticultural delight. Some of the trees are ancient survivors from the field boundaries and Victorian villa grounds that predated the museum, giving the place a sense of deep-rooted continuity that you don't often find in a city park.
There are formal planted areas, a nature trail, bee-friendly planting schemes, and an animal walk where you'll find sheep, goats, alpacas, rabbits, guinea pigs, and chickens going about their daily business in blissful ignorance of the city surrounding them.
In spring, the gardens burst into colour. In summer, families spread out across the lawns. In autumn, the trees turn extraordinary shades of amber and gold against that wide London sky. And in winter, just avoid the rain by stepping inside!
The Butterfly House
If the gardens are a delight, the Butterfly House is something close to magical. Housed in a warm, tropical greenhouse, hundreds of free-flying butterflies circle overhead, settle on your shoulders, and drift past at eye level in a dizzying, gorgeous cloud of colour. There are exotic species from around the world, and visitors can pick up a spotting card to try and identify the different varieties (which is easier said than done, when they won't stop moving).
There is also a puparium where you can observe the full life cycle, watching cocoons at various stages and occasionally, if you time your visit right, witnessing a newly hatched butterfly take its very first flight. Staff are on hand to explain what's happening, and the whole experience has a quality of quiet wonder that is hard to find anywhere else in the city. A small charge applies, but it is absolutely worth it.
The Aquarium
Below ground, the Horniman's Aquarium has been a fixture of the museum almost since it first opened, which makes it one of the oldest public aquariums in London. Fifteen exhibits take you on a journey through aquatic environments from a British freshwater pond right through to the vivid, jewel-bright coral reefs of Fiji. Fish, jellyfish, coral, frogs, and other aquatic creatures populate each display, and the staff are actively involved in ongoing research into coral reproduction and jellyfish biology. It is quietly fascinating, beautifully presented, and well worth the modest entrance fee.
Why It's So Good for Children
Here's the truth about the Horniman: it is one of the best places in London to bring children, full stop. Not because it is dumbed down or overly child-focused but because it combines genuine intellectual richness with the kind of hands-on, sensory experiences that children actually enjoy and respond to.
Where else can a child hand-feed a goat in the Animal Walk, watch a butterfly emerge from its chrysalis, peer through the glass at a coral reef, and then spend twenty minutes banging things in the Musical Instruments Gallery, all in a single afternoon? The collections are genuinely interesting to young minds precisely because they are so strange - there’s always something new around the next corner, always another object to ask questions about. The interactive exhibits are thoughtfully designed, and the staff are knowledgeable and approachable.
And the gardens give children the thing they need most of all: room to run. Wide open lawns, hidden corners, and views that make you feel on top of the world, it's the perfect outdoor space for children.
And almost all of it, it should be noted, is completely free. For a full family day out in London, the kind that actually leaves everyone feeling enriched rather than exhausted and bankrupt, a visit to the Horniman is almost impossible to beat.
Getting There
The Horniman is a five-to-ten-minute walk from Forest Hill station, on the overground's Windrush Line. From London Bridge it's roughly twenty minutes by train. It is, in other words, very accessible and entirely worth the journey.
So if you find yourself in the British capital and you're looking for something a little off the beaten track, something that will surprise you, delight you, and send you home with more questions than you arrived with, head for Forest Hill. Frederick Horniman wanted to bring the world to south-east London. More than a century later, he's still doing exactly that.
