Loch Ness
Scotland's deepest loch, home to over a century of modern sightings of "Nessie," a creature whose legend stretches back to a sixth-century account by St. Columba.
Field Guide Entry
Origin Story
The earliest account dates to 565 AD, when a biography of St. Columba describes him calming a "water beast" in the River Ness. The modern wave began in 1933, after a new road opened along the loch's shore and a local couple reported a large creature crossing it. The Inverness Courier ran the story under the headline "Strange Spectacle on Loch Ness." In 1934, a photograph attributed to a London surgeon, showing a long neck breaking the surface, became the creature's defining image for the next sixty years.
Evidence & Claims
Sonar surveys have been conducted on the loch since the 1960s, producing occasional unexplained contacts. A 1972 expedition produced a widely circulated "flipper" photograph. Hundreds of amateur sightings and photographs have been logged by the Official Loch Ness Sightings Register. Some researchers have proposed a large eel or wandering sturgeon as a basis for at least some reports.
Skeptical Explanations
In 1994, one of the men involved in the 1934 photograph confessed shortly before his death that it depicted a toy submarine fitted with a sculpted head. Extensive sonar surveys (BBC, 2003) and a 2018 environmental DNA survey of the loch found no genetic evidence of any large, unknown animal. Boat wakes, floating logs, and standing waves explain many reported sightings.
Visiting Information
The Loch Ness Centre in Drumnadrochit covers the loch's natural history and the search for the monster. Nessie-hunting boat cruises run from Inverness and Drumnadrochit through the summer. Urquhart Castle, on the loch's shore, is the most popular vantage point for a sighting.
