GOOGLEEARTH This mysterious dome structure hints at an ancient civilisation dwelling in Antarctica

What apperars to be the remains oval shaped “building” is 400ft across and appears to have all the hallmarks of being a sizeable, man-made construction - similar to a mediaeval motte and bailey castle. If true, it would reshape everything scientists thought they knew about humanity’s past as it would prove people inhabited what was previously thought to be a desolate region.

Satellite imagery clearly shows the structure, which closely resembles the ruins of a once giant building. It is so symmetrical it has raised questions as to whether nature alone could have designed it.

Scientists initially thought the discovery could be a sastrugi – a natural phenomenon formed by years of being battered by strong, freezing winds and heavy snowfall. But sastrugies always form a distinctive shape based on the direction of the wind and rarely appear as a distinct oval, such as the mystery formation in the satellite image. Ancient civilisations in Antarctica have long been rumoured to have existed, with people pointing to a map drawn in 1513 by Turkish admiral Piri Reis as a clear sign of historic life.

The map shows Antarctica drawn impeccably well, despite it not officially being discovered until 1818. This dome-like structure is not the first discovery to raise questions about advanced ancient civilisations living in the area. A pyramid also appears to have been discovered poking out of the snow, with its distinctive triangular, symmetrical shape are clearly at odds with its surrounding environment.
