In the 21st century, scientists have achieved results that until recently seemed unrealistic. You might think that there is nothing unsolved in the world at all. True, this is not so - the age of some buildings is estimated at thousands of years. The origin of such finds is unknown to this day. Scientists are sincerely perplexed how people managed to create such structures, which are not simple in their technology.
Burial complex in the Bru-na-Boyne valley
Burials were discovered near Dublin - only 40 necropolises. In total, the structure covers an area of 10 sq. m.
True, it is assumed that the complex itself is much larger. The most ancient necropolis, according to archaeologists, was built 5 thousand years ago. In fact, this is one of the world's oldest landmarks. According to scientists, this is not just a cemetery, but also a temple. They also found an altar at the end of the corridor and occupying 19 meters. It is difficult to imagine that all this was built by people - historians cannot understand where the mysterious buildings came from.

Not far from the city of Phonsavan, archaeologists have found an interesting place. The territory itself is deserted, but there are dozens of stone structures in the form of jugs ranging in size from 20 cm to 3.5 m.
The largest buildings weigh about 6 tons. There are about five hundred of them. Scientists don't yet know where they came from. It was possible to find out only the age - 2.5 thousand years.
There are many legends associated with the valley. Local residents believe that stone stupas were created by giants who previously inhabited our planet. Scientists think that the buildings were intended for burial, however, they cannot prove it. But the most amazing thing is that in this city and near it, there have never been any stone deposits.
Columns in Shravanabelagol
The unusual columns have become famous lately. Many people want to see with their own eyes the unique carved structures.
Scientists are at a loss as to how the ancient masters were able to reproduce such thin and smooth sections. Now there is no person who can manually reproduce similar columns. And how it was once built remains a mystery.
Fairy Houses in Italy
There are many monuments of ancient civilizations in Italy. Especially interesting are those that are located on the island of Sardinia - their locals consider them to be the houses of fairies.
Yes, you cannot name them otherwise, because these mini-buildings have tiny windows and an entrance - a person clearly cannot fit in them. There are about 2.8 thousand such structures here. According to scientists, their approximate age is 5 thousand years. The houses are found in large boulders and sheer cliffs. On the walls of each building there are inscriptions in an unknown language.
Sometimes the structures cause bewilderment among the archaeologists who have seen them. Fairy houses, unusual columns, and even jugs of different sizes - all this remains a mystery to each of us.
