It sounds wild, but yes—a white bear, probably a polar bear, once swam and fished in the Thames under royal orders. The Tower of London housed this unlikely guest, and Londoners flocked to the river to catch a glimpse.
Ever wondered how a royal gift from the 1200s could turn the Thames into such a spectacle? Here’s the story.
Historians have pieced together what happened, but some details still spark debate—was it really a polar bear? The Tower’s menagerie kept all sorts of exotic creatures, but this bear stood out. I mean, who wouldn’t remember seeing a polar bear in medieval London?
A Polar Bear in the River Thames: Fact or Fiction?
Let’s start with the facts. In 1252, King Henry III received a pale bear—almost certainly a polar bear—as a royal gift.
The Arrival of the White Bear in 1252
King Haakon IV of Norway sent Henry III a white bear in 1252. Back then, people called polar bears “white bears,” and they were rare enough to impress any royal court.
This bear joined the Tower’s menagerie. The year 1252 really marks the moment when the Tower started showing off Arctic animals—something most Londoners had never imagined.
King Haakon IV’s Royal Gift to Henry III
Haakon IV didn’t just send any old animal—he sent something that screamed power and status. Only someone with connections to Greenland could pull off a gift like this.
Henry III accepted the bear, but quickly realized it wasn’t cheap to keep. He got the sheriffs of London to help cover the costs, which tells you just how much effort went into maintaining this royal showpiece.
Swimming and Fishing in the Thames
In 1253, Henry gave orders: let the bear swim in the Thames. They muzzled the bear and attached it to a long chain, so it couldn’t wander off.
Picture this: a polar bear, chained but still powerful, diving for salmon in the Thames. It must have been a wild scene.
Crowds gathered to watch. For 13th-century Londoners, seeing a polar bear fishing in their own river was probably the highlight of the week.
The Bear’s Norwegian Handler and Public Spectacle
A Norwegian handler managed the bear and likely came over with it from Norway. The sheriffs had to pay for both the bear’s upkeep and the handler’s clothing.
At first, the sheriffs didn’t provide enough money, so the crown had to bump up the allowance. Managing a polar bear wasn’t cheap or easy.
The bear didn’t just sit in a cage—it walked the Tower grounds, chained and closely watched. The handler’s presence, the royal orders, and the public displays made this bear a real celebrity in medieval London.
Soon, the menagerie picked up even more exotic animals. An elephant arrived in 1255 and quickly stole the spotlight from the bear.

The Tower of London Menagerie and Its Exotic Residents
The Tower wasn’t just a prison—it became famous for its wild collection of animals. Some stayed for years; others, not so much.
Establishing the Royal Menagerie
The menagerie goes back to the early 1200s, when kings started collecting exotic animals to show off their power. In 1235, Henry III got animals from Frederick II—probably three lions, though the records called them “leopards.”
The collection grew with each royal gift. In 1252, Haakon IV sent the white bear, and in 1255, Louis IX of France sent an elephant.
Animals lived inside the Tower walls and in nearby yards. Monarchs treated them like royal property, hired keepers, and used the menagerie to impress both foreign visitors and locals.
Lions, Leopards, and Other Royal Beasts
If you’d visited back then, you’d see lions, “leopards” (often lions), lynxes, and some strange birds. The polar bear, with its daily trips to the Thames, became a crowd favorite for a while.
The elephant’s arrival in the 1250s really shook things up, and over the centuries, the collection grew to include ostriches, tigers, and other oddities. For Londoners, these animals were a rare thrill.
Sometimes crowds gathered just to watch the animals, so the menagerie was both a public show and a private royal collection.
Caring for the Tower Animals
Keepers worked long hours feeding and looking after the animals. Kings paid for stewards and specialized keepers to handle the daily grind—meat, hay, and whatever else the animals needed.
The city chipped in too. Officials had to buy food, chains, muzzles, and even build shelters for some creatures.
The polar bear’s care really showed the limits of medieval animal-keeping. Tethered and allowed to fish in the Thames, it got at least some of what it needed. Veterinary skills were pretty basic, so keepers mostly relied on observation, trial and error, and practical tricks—muzzles, chains, and sturdy pens—to keep things under control.
From the Tower to London Zoo
You can actually draw a pretty clear line from the old Tower menagerie straight to today’s zoos.
By the 19th century, people started to really worry about animal welfare. Complaints about cramped conditions got louder, and eventually, they shut down the menagerie in 1835.
They moved the animals to new places that could actually care for them and let scientists study them properly.
This change sparked the creation of the Zoological Society of London. It also led to the public London Zoo, which focused on education and conservation.
The move signaled a shift—from royal entertainment to a more scientific, public-minded approach to keeping animals.
