The Lost Continent Beneath Europe That No One Knew About Until 2017

For centuries, the idea of lost continents has fascinated people. But in 2017, scientists confirmed something incredible—there really is a lost continent hidden beneath Europe. And while it’s not the mythical Atlantis, it’s still one of the most astonishing geological discoveries of our time. This lost land, called Greater Adria, was a continent-sized landmass that existed over 100 million years ago before it was gradually swallowed up by tectonic forces. Parts of it still survive today. However, you’d never know just by looking at a modern map.

How Do You Lose an Entire Continent?

Unlike Atlantis, which supposedly disappeared overnight in some great cataclysm, Greater Adria’s fate was much slower. It was also much more scientifically explainable. It was once a large, shallow landmass located in what is now the Mediterranean region. About 240 million years ago, it was part of the supercontinent Pangea. As Pangea broke apart, Greater Adria split from what is now Africa and started drifting north.

For millions of years, it was a thriving landmass, likely covered in tropical islands and coral reefs. But as it collided with the European continent between 100 and 120 million years ago, the relentless forces of plate tectonics forced most of Greater Adria underneath Europe. It was buried deep within the Earth’s crust. The only visible remnants today? Parts of Italy, Croatia, and the Balkans, which were once part of its surface.

Why Did It Take Until 2017 to Discover It?

You’d think an entire continent wouldn’t be that easy to miss, but the problem is that Greater Adria didn’t sink into the ocean—it was subducted. This means it was forced under another tectonic plate and crushed into the Earth’s mantle.

For decades, geologists suspected something was hiding beneath southern Europe because of the complex, jumbled rock formations found across the region. However, it wasn’t until 2017 that researchers from Utrecht University in the Netherlands were able to piece together the full story. Using advanced seismic imaging and plate reconstruction models, they traced the movements of Earth’s plates over the past 240 million years. They confirmed that an entire continent had been buried under modern-day Europe.

According to Douwe van Hinsbergen, the geologist who led the study, Greater Adria is the most fragmented and deformed continent ever found. This explains why it took so long to identify. Over time, parts of it were scraped off and forced upwards, creating some of Europe’s most dramatic mountain ranges, including the Alps and the Apennines.

Where Is Greater Adria Today?

Most of Greater Adria is still buried deep beneath Europe, compressed into the layers of the Earth’s crust. But not all of it disappeared. Some of the rocks from this ancient continent were pushed up and now form parts of:

The Italian Alps – Many of the limestone formations here once belonged to Greater Adria’s coral reefs.

The Balkans – Pieces of Greater Adria’s landmass can be found scattered throughout Croatia and Serbia.

Southern Spain and Greece – Geologists have identified fragments of Greater Adria’s crust that were scraped off and folded into the land we see today.

So while Plato’s Atlantis may have been a myth, the idea of ancient lands disappearing beneath the sea? That’s no longer just a story. It’s real. Scientists even believe there could be other hidden landmasses buried beneath Earth’s surface, waiting to be discovered.
