Jersey never quite fits the mould. Ask most people what they know about Jersey and they’ll mention golden beaches, fresh seafood … and probably Jersey cows – and they wouldn’t be wrong. But some of the most fascinating facts about Jersey are the ones you didn’t know. Scratch beneath the skin of this small but extraordinary Channel Island and you’ll uncover a world of secrets, surprises and stories that most visitors never expect.
Here are 12 things you almost certainly didn’t know.
1. Jersey gave America one of its states
During the English Civil War, this tiny island sheltered the future King Charles II on two separate occasions. It was from the Royal Square in St. Helier that the King was first publicly proclaimed King of England in 1649, following the execution of his father. In gratitude, land in the American colonies was gifted to the island’s then Bailiff and Governor, Sir George Carteret, who named his new territory New Jersey.
2. Your jumper was named after us
That well-known knitted top hanging in your wardrobe? It owes its very name to this island. Jersey has a centuries-old tradition of wool knitting stretching back to the 15th century, when the wives of local fishermen and sailors crafted close-fitting garments from natural wool. Practical, water-resistant and wonderfully warm, these island-made knits caught on across Britain and beyond. By the mid-19th century, the word ‘jersey’ had entered the English language as a common noun for any knitted garment – and it’s been there ever since.
Fun Fact!
The craft of knitting was so loved that the Government of Jersey once banned knitting during harvest season to stop farmers abandoning their fields – a law that, technically, remains on the books to this day.
3. The capital of Jersey was founded and named after a man who carried his own head
The origin story of St. Helier is extraordinary. The town and parish take their name from Helier, a sixth-century hermit monk from Belgium who settled on a rocky tidal islet in St. Aubin’s Bay, where he spent years in prayer, warning island communities of approaching sea raiders.
Legend holds that when pirates killed him around AD 555, he had the miraculous strength to pick up his own severed head and walk to shore. The rocky hermitage where he once lived still stands today within the grounds of Elizabeth Castle and, every year on the 16 July, a pilgrimage makes its way across the sand to pay tribute.

4. A prehistoric forest is buried beneath one of our beaches
When the tide and swell strip back the sands at St. Ouen’s Bay, something remarkable is occasionally revealed – the exposed roots, tree stumps and peat beds of an ancient, submerged forest, dating back to between 6073 and 5848 BC.
What is now one of Jersey’s most beloved beaches was once a freshwater marshland and fen, home to woodland of oak, ash, hazel, elm and pine. As sea levels rose over thousands of years, those forests were slowly swallowed by sand and sea – and there they have quietly remained ever since.
Look closely and you can still make out the root systems and bases of ancient tree trunks locked into the dark peat, preserved for over eight thousand years beneath your feet. It’s the kind of discovery that stops you in your tracks and reminds you that Jersey’s story stretches far, far deeper than even its oldest buildings.
Fun fact!
Local legend tells of an entire manor house, its farmland and surrounding oak forest being swallowed overnight by a catastrophic storm in 1356, leaving nothing but open sea where fertile fields once stood.
The tale of La Brecquette has been repeated for centuries – but the truth, uncovered by archaeologists from the Société Jersiaise in 2007, is arguably more interesting. It wasn’t a flood at all. Evidence suggests a great sandstorm buried the farmstead, and the owner simply packed up his dressed stones, moved inland and rebuilt his home as far from the coast as he could get. The granite foundations he left behind are still down there, buried beneath a St. Ouen’s potato field to this day.

5. Witches’ seats are hidden on old Jersey chimneys
According to history books, Jersey was considered the ‘witch-hunting capital of Europe’ in the 1600-1700’s. The accused were held at Mont Orgueil Castle until their trials, which were held before Jersey’s Royal Court.
Today, as you wander our tiny island, look carefully at some of Jersey’s older granite houses and you’ll spot flat stones jutting from chimneys.
According to island folklore, these were built to give travelling witches somewhere to rest during their nightly flights, keeping them too comfortable to cause mischief inside the house.
6. The greatest treasure hunt in European history happened in Jersey
In 2012, a quiet field in Grouville revealed one of the most extraordinary discoveries in European archaeology – Le Câtillon II – the largest Iron Age coin hoard ever found in Western Europe.
For more than 30 years, local metal detectorists Reg Mead and Richard Miles searched for a rumoured treasure buried in a broken pottery jar. When they finally uncovered the site, what began with just five coins turned into a five-day excavation of a one-tonne mass of precious metal.
The hoard contained around 69,000 Celtic gold and silver coins, alongside gold torques, silver bracelets, rings and glass beads. Carefully lifted from the ground in one intact block, it has since been meticulously scanned, mapped and conserved. Researchers now believe it may actually be two separate hoards buried together.
Today, this remarkable treasure is in the care of Jersey Heritage, with new research still uncovering its secrets.

7. A Jersey girl helped turn Boots into a British high street icon
Every time someone walks into a Boots on a British high street, they are stepping into a story that began in a St. Helier bookshop. Florence Rowe was born in 1863, the daughter of a Queen Street bookseller, and grew up serving customers from behind her father’s counter. In 1885, a burned-out Nottingham businessman named Jesse Boot arrived on the island when he met Florence, and the two were married the following year. Her sharp retail instincts and creativity helped transform Boots from a small chain of chemists into a national institution – introducing cosmetics counters, stationery, gifts and lending libraries to stores across Britain.
The couple never forgot Jersey. Jesse gifted the island the FB (Florence Boot) Playing Fields in St. Clement – still one of Jersey’s most beloved sporting venues today – and built 22 homes for large, working-class families in Grève d’Azette, named the Florence Boot Cottages in her honour.
Florence, meanwhile, asked her husband for an unusual birthday gift – her very own bay. In February 1923, Jesse duly purchased the land above the beautiful and secluded Beauport Bay and gave it to her. It was Florence’s wish that the bay eventually be gifted to the people of Jersey, and in 1950 her son honoured that wish. She also gifted the gardens of her own home at Villa Millbrook to the island for future generations to enjoy, and they were christened Coronation Park. Walk through Coronation Park, spend an afternoon at Beauport or watch an athletics meet at the FB Fields and you are, in a very real sense, walking through their legacy.

8. A church in St. Lawrence was designed by the world’s greatest glassmaker, Lalique
From the outside, St. Matthew’s Church (also known as the Glass Church) in Millbrook looks like a modest, unassuming building. Step inside, though, and you’ll find yourself in one of the most extraordinary interiors in the island.
In 1934, Florence Boot commissioned the legendary French glassmaker René Lalique to transform the entire church in her late husband Jesse Boot’s memory. The result is breathtaking – a towering frosted glass altar cross, luminous Art Deco angels, and a glass font signed by Lalique himself. No similar Lalique commission survives anywhere else in the world. The moulds used to create each piece were destroyed as the work was completed, meaning what you see here can never be replicated.
9. Jersey prints its own banknotes
Cash comes with character in Jersey. The island issues its own currency, the Jersey Pound, which sits at the same value as the British Pound but carries a distinctly local identity.
Look closely at the notes and you’ll spot iconic Jersey landmarks, the island’s famous Jersey cows and the smiling portrait of the late Queen Elizabeth II. It’s a small detail that adds a sense of place to every purchase.
Jersey is also one of the last places where you’ll still find a £1 note in circulation – a charming throwback that makes even paying for a coffee feel uniquely Jersey.
10. Jersey’s nickname comes from a tiny local celebrity – the toad
Jersey is the only Channel Island where toads naturally live. The unique species, known locally as the ‘Crapaud’, can’t be found anywhere else in the British Isles.
Over time, the island’s association with these small amphibians gave Jersey its charming nickname. Locals even celebrate the toad as a symbol of the islands, appearing in local stories, art and heritage. Spotting a Crapaud in the wild is a special little reminder of Jersey’s distinctive wildlife.
11. A local caddie from Jersey became one of the greatest golfers of all time
Harry Vardon grew up in Grouville, Jersey, caddying for pocket money at The Royal Jersey Golf Club but then went on to win the Open Championship six times – a record that has never been beaten.
In 1913, Vardon – considered the greatest golfer in the world – was beaten in a playoff at the US Open by a 20-year-old amateur caddied named Francis Ouimet, in one of sport’s greatest ever upsets. The story later inspired the Disney film The Greatest Game Ever Played.

12. Jersey has its own ancient language – and it outwitted the Nazis
Jèrriais, Jersey’s Norman language, has been spoken on the island for over a thousand years. Descended from the French dialect brought by the settlers of William the Conqueror, it remains visible today in the island’s road signs, place names and the work of dedicated language preservationists.
Its most remarkable chapter, however, came during the Nazi Occupation of World War II, when islanders used Jèrriais to communicate without their occupiers understanding a single word. Look out for it as you explore – it’s the island’s living linguistic fingerprint.
Jersey is full of surprises – come and find your own
The facts, the legends and the stories are all here waiting – but the best way to discover Jersey is to experience it for yourself. Whether you’re drawn by the history, the food, the coastline or the characters, there’s always something on this island that you never quite expected.
