1. Birds of moa
Moa are flightless birds that lived in New Zealand and became extinct around 1500, destroyed (according to one theory) by the Maori aborigines. During one of the expeditions, scientists came across a huge part of a bird's leg, which is incredibly well preserved.
2. Temple complex of Sacsayhuaman, Peru
This temple complex amazes with its impeccable masonry without a drop of joint mortar (even a piece of paper cannot be inserted between some of the stones) and how perfectly the surface of each block is processed.

3. Gate of the Sun, Bolivia
The Gates of the Sun are located in Tiwanaku - the most ancient and mysterious city. Some scholars believe that in the first millennium AD, it was the center of a huge empire. There is still no idea what the drawings on the gate mean. Maybe they carried some kind of astrological and astronomical value.
4. Longyu Grottoes, China
The grottoes were carved into the sandstone by people - it was a complex work in which thousands of Chinese were sure to take part, but nowhere is there any mention of these grottoes and how they were created.
5. Obelisk, Egypt
The obelisk began to be cut right into the rock, but cracks began to appear along it. It was left unfinished. The dimensions are simply stunning!
6. Underwater city, about. Yonaguni, Japan
The complex was accidentally discovered by diving instructor Kihachiro Aratake. This underwater city destroys all scientific theories. The rock in which it was carved went under water about 10,000 years ago, that is, much earlier than the erection of the Egyptian pyramids. According to the modern views of some scientists, in that distant era, people huddled in caves and only knew how to collect edible roots and hunt wild animals, and not build stone cities.
7. Mohenjo-Daro (Hill of the Dead), Pakistan
For many decades, archaeologists have been worried about the mystery of the death of this city. In 1922, the Indian archaeologist R. Banarji discovered ancient ruins on one of the islands of the Indus River. Even then, questions arose: how was this big city destroyed, where did its inhabitants go? Excavations gave no answer to any of them.
8. L'Anse aux Meadows Settlement, Canada
This settlement was founded by the Vikings about 1000 years ago. This means that they got to North America much earlier than Christopher Columbus was born.
9. Tunnels of the Stone Age
The discovery of a vast network of underground tunnels (stretching across Europe from Scotland to Turkey) suggests that Stone Age people spent their days not only hunting and gathering. But the real purpose of the tunnels is still a mystery. Some researchers believe that their task was to protect people from predators, others - that people traveled through this system, protected from weather and war.
10. Giant stone balls of Costa Rica
Mysterious stone formations of ideally round shape intrigue not only with their appearance, but also with their incomprehensible origin and purpose. They were first discovered in the 30s of the XX century by workers when clearing the jungle for banana plantations. Local legends said that gold must have been hidden inside the mysterious stone balls. But they were empty.
