The famed lost city of Atlantis may have been found in a rather unlikely place - the Sahara Desert.

According to a YouTube clip uploaded earlier this week that's found a massive audience online, the remains of the ringed city Plato spoke of in the fourth century BC can be found in the African country of Mauritania.

And it's been hiding in plain sight this whole time.

"We've been looking in all the wrong places for its location since everyone assumes it must be under the ocean somewhere, such as in the depths of the Atlantic Ocean or the Mediterranean Sea," says the host of Bright Insight YouTube channel, known only as Jimmy.

Instead he proposes a strange formation known as the Richat strucuture, or the 'Eye of the Sahara', is the mythical city's true location.
