There are many mysterious places and structures on our planet that baffle many scientists from all over the world. They cannot understand why it was created, and what secrets can be kept in them. One of these monuments of ancient people is a building located in Ireland - Newgrange.
This megalithic structure was discovered in 1655 by the English landowner Charles Campbell. It was unearthed by workers looking for stones for various needs. Immediately after its construction, it was a tall structure, but over time, due to subsidence of the soil, it went underground. In our time, many scientists are trying to determine the purpose of this megalith, but opinions are constantly diverging. According to the latest archaeological research, it was built about 5000 years ago, and is older than the Cheops pyramid by as much as 500 years. The material used by the ancient builders to build this monument is stone, earth and rubble. Incredibly, in the entire history of its existence, the roof of this monument has never leaked, and still does not let moisture inside. The height of the embankment of the structure is 13 meters, and its diameter is 85 meters.
The inner structure of this mysterious megalith consists of a narrow corridor, 18 meters long, leading to a special chamber. In it, in the very center, there is a large bowl, and around it, in the stone walls, huge niches are carved, the walls of which have various paintings made on stones. In this room, there is a stepped vault, which is made by stone monolithic columns, weighing from 20 to 40 tons, each. Their shape is very interesting, as they taper towards the top. The very dome of this room goes deeper upward, forming a hexagonal shaft, 6 meters deep.
The main mysteries of this structure is a certain effect created by the sun's rays. The corridor that leads to the burial chamber has a southeast direction, from where the Sun begins its ascent, precisely on the day of the winter solstice. Above its entrance, a small hole was made, about 20 centimeters wide, through which sunlight (rays) enters the interior and illuminates it for 20 minutes. This is a grandiose spectacle that everyone cannot see.
Scientists cannot determine the belonging of this structure to this day. Their opinions were divided, some consider it to be a burial structure, others attribute it to a ritual room with an astronomical focus. But the mystery, its construction and purpose has not yet been solved. Now it is a UNESCO-protected museum and one of the oldest monuments in Europe.
