Conspiracy theorists speculate that a civilization might have flourished in Antarctica thousands of years ago at a time that the climate of the environment was much different than today. This means, according to conspiracy theorists, that Antarctica was not always frozen wasteland and that the continent was warm enough in the past to sustain large and complex technological human societies that created impressive monuments, such as temples, castles and cities. But we are unable to see the remains of ancient Antarctica civilization today because most of the ruins are buried in thick layers of ice and snow.
But scientific researchers have denied the sensational conspiracy theory claims, saying that the alleged artificial structure, claimed to be a castle or fort, is in fact part of the natural Antarctica landscape known as a sastruga, the Daily Mail reports.
Sastrugi are irregular ridges on snowy surfaces formed through the battering action of freezing winds and heavy snowfall in the polar and cold temperate region.
But conspiracy theorists rejected the explanation offered by scientific researchers, arguing instead that the shape of sastrugi, determined by the direction of wind, is very rarely oval-shaped. The symmetry of the 400-ft structure is also not characteristic of sastrugi. The symmetry shows that it is not part of the natural landscape of the area but an artificial structure created by intelligent designers, conspiracy theorists claimed.
Some theorists insisted that compelling evidence that people have known about lost ancient civilizations on Antarctica for centuries comes from a map drawn in 1513 by Turkish admiral Piri Reis. The map identifies Antarctica landmass unambiguously despite the official version of history that Antarctica was discovered much later.
