Believe it or not, the story doesn't start with a grainy black-and-white photo from the 1930s. Most people think Nessie is a modern invention, a product of clever Scottish tourism marketing or a collective hallucination fueled by too much whisky. But if you want to know when was the Loch Ness monster first seen, you have to go back way further than the invention of the camera. We’re talking nearly 1,500 years back.
It’s wild.

The very first recorded sighting of a "water beast" in the River Ness—which flows into the loch—dates back to 565 AD. This isn't some tabloid rumor; it’s actually documented in a hagiography. A what? A biography of a saint. Specifically, the Life of Saint Columba, written by Adomnán, the Abbot of Iona.
The Sixth-Century Encounter That Started It All
Here is the scene. Saint Columba, an Irish missionary credited with spreading Christianity to Scotland, was traveling through the land of the Picts. He came across a group of locals burying a man by the River Ness. They told Columba that a "water beast" had snatched the poor guy and mauled him to death while he was swimming.
Columba didn't blink. He sent one of his companions, a brave soul named Lugne Mocu Min, to swim across the river to fetch a boat. Predictably, the monster saw a fresh snack and surged to the surface with a roar. Adomnán describes the beast as having a massive open mouth.
Then it gets weird.
Columba raised his hand, made the sign of the cross, and commanded the beast to "go no further." According to the text, the monster fled as if it were being pulled back by ropes. It’s a great story. But is it a biological record? Probably not. Back then, "monster" stories were often used as metaphors for the triumph of faith over paganism or the dangers of the untamed wilderness. Still, that’s the official "first" on the books.
The 1933 Explosion: When Nessie Went Viral
Fast forward over a thousand years. For centuries, the Highlands were full of local folklore about "kelpies" or water horses. These were shapeshifting spirits that lured travelers to their deaths in the deep, cold waters of the Scottish lochs. But the modern obsession—the one that actually makes people fly to Inverness with binoculars—really kicked off in 1933.
Why then? Simple: infrastructure.
A new road had just been completed along the northern shore of the loch. For the first time, people had an unobstructed view of the water while driving. On April 14, 1933, Aldie Mackay, who ran the Drumnadrochit Hotel, was driving with her husband when she saw something massive splashing in the center of the loch. She described it as an "enormous animal" resembling a whale.
The Inverness Courier ran the story. The editor, Evan Barron, used the word "monster." That one word changed everything.
Suddenly, everyone was looking at the water. A few months later, George Spicer and his wife claimed to see a prehistoric-looking creature lurch across the road in front of their car and disappear into the loch. Spicer described it as having a long neck and a bulky body. It looked, in his words, like a "scenic railway." If you've ever seen a vintage roller coaster, you get the image.

The Surgeon’s Photograph and the Great Deception
You’ve seen the photo. The elegant, swan-like neck rising out of the ripples. It’s the definitive image of the Loch Ness Monster. For decades, this 1934 picture, supposedly taken by Robert Kenneth Wilson, a London gynecologist, was the "smoking gun."
It wasn't real.
In 1994, a man named Christian Spurling confessed on his deathbed that he had helped his stepfather, Marmaduke Wetherell, faked the photo. Wetherell had been humiliated by the Daily Mail after he found "monster tracks" that turned out to be made by a dried hippo-foot umbrella stand. He wanted revenge.
They used a toy submarine from Woolworths and molded a head out of wood putty. They weighted it down, put it in the water, and snapped the shot. It’s a bit heartbreaking, honestly. The most famous evidence for the monster was literally a bath toy. But even after the hoax was exposed, the world didn't stop believing.
What Are People Actually Seeing?
Loch Ness is a weird place, geographically speaking. It’s 23 miles long and incredibly deep—nearly 800 feet in some spots. It contains more fresh water than all the lakes in England and Wales combined. Because the water is filled with peat particles from the surrounding hills, visibility is almost zero. It’s a giant, murky abyss.
When people ask when was the Loch Ness monster first seen, they’re often looking for a biological explanation. Could it be a plesiosaur? That’s the popular theory. A prehistoric marine reptile that somehow survived the extinction of the dinosaurs.
Scientists, however, are skeptical. In 2019, Professor Neil Gemmell from the University of Otago led a massive environmental DNA (eDNA) study of the loch. They took 250 water samples from different depths and locations. They didn't find any dinosaur DNA. No shark DNA. No catfish DNA.
What did they find? Eels. Lots and lots of eels.
Gemmell suggested that the "monster" might just be giant European eels (Anguilla anguilla). While most eels don't get much bigger than a few feet, some people believe that in the cold, isolated depths of the loch, a few individuals might have grown to monstrous proportions. It’s a bit less romantic than a dinosaur, but it’s a lot more plausible.
Why the Legend Persists
There’s a psychological element to this. It's called pareidolia—the human tendency to see patterns where none exist. On a choppy day at Loch Ness, a floating log, a boat wake, or even a line of ducks can look remarkably like a multi-humped serpent.
Boat wakes are a big one. Because the loch is long and narrow, waves can bounce off the steep underwater walls and meet in the middle, creating a standing wave that looks like a creature swimming against the current. It’s an optical illusion that has fooled thousands of tourists.
Then there’s the "Deepscan" operation of 1987. A fleet of boats equipped with sonar swept the loch. They actually picked up a "large unidentified object" that was moving. Was it a monster? Or just a big salmon or a seal that took a wrong turn from the sea? We don't know. That’s the magic of it.
Modern Sightings and Digital Proof
Even in the age of 4K smartphone cameras and satellite imagery, the sightings haven't stopped. The Official Loch Ness Monster Sightings Register (yes, that’s a real thing) still records several "credible" sightings every year.
In 2023, the loch saw its biggest organized search in 50 years. Hundreds of volunteers lined the shores, and researchers used thermal imaging drones and hydrophones (underwater microphones). They heard four distinct "gloops." But they didn't see a neck.

People often ask me if I believe. Personally? I think the "monster" is the loch itself. It’s a dark, atmospheric, and deeply mysterious body of water that makes your imagination run wild. Whether there's a biological anomaly living down there or just a lot of very large eels and weird wave patterns, the mystery is far more valuable than the truth.
Actionable Insights for Your Visit
If you’re planning to go to Scotland to see where the Loch Ness monster was first seen, you need to manage your expectations. Most "sightings" happen under very specific conditions.
- Go to Urquhart Castle: This is where many of the most famous sightings have occurred. The ruins sit right on the deepest part of the loch.
- Watch the weather: The best time to see "humps" is on a calm, overcast day when the water is like glass. That’s when surface disturbances stand out the most.
- Visit the Loch Ness Centre: Located in Drumnadrochit, it’s actually a very scientific, sober look at the history and biology of the loch rather than a tourist trap.
- Scan the River Ness: Remember, the first sighting wasn't in the loch itself, but the river. Walk the banks in Inverness; you might see a seal or a large salmon that helps you understand how the legend started.
The search for Nessie is a lesson in human curiosity. We want the world to be more mysterious than it is. We want there to be a prehistoric beast lurking in the Scottish Highlands because it makes the world feel bigger. Whether you’re looking at a 6th-century manuscript or a 2026 satellite image, the answer to when the monster was first seen is simple: the moment we decided to look into the dark and imagine what might be looking back.
To dive deeper into the history, check out the archives of the Inverness Courier or read Adomnán's Life of Saint Columba for the original account. You can also monitor the live "Nessie Cam" online, which streams the loch 24/7. Just don't expect to see a plesiosaur on your first watch.
