Mysterious circular pits appear in Austria

Recently, the media reported on the fact that an Austrian farmer had discovered a mysterious, round hole deep inside his farm after just one night.

Speaking to Austrian Times, Franz Knoglinger said: 'I was looking for a missing cat and suddenly saw that hole. Curious about its depth, I threw a stone down and heard a sound like metal echoing after a while. I found it very deep. '

Then, Knoglinger brought the rope with the magnet down to the pit, and he concluded that the object at the bottom was metal.

The round and deep hole is controversial.

Immediately, this mysterious hole attracted the attention of scientists as well as alien hunters. One of the hypotheses is the appearance of UFOs.

The hole is perfectly circular. It made many people think of a spacecraft under an underground storage that had been forgotten for a long time. This is an explanation that seems to have been defaulted in recent years for any unidentified metal object or round shape.

However, a local historian gave the opposite evidence. According to him, this hole does not have to appear after a night as Knoglinger assumed, but has existed for decades.

In fact, half a century ago, an oil company had used oil drilling machines. That time, the large metal drill was stuck in this area, unable to be removed. That's why the magnet is sucked down.

Years later, this place became an agricultural land and gradually, people no longer remember them when the grass covered everywhere.
