“Stonehenge” is the name given to a megalith (a large construction) located in Wiltshire, England, consisting of a series of buried stones, organized in a circular way. This, along with other remains of prehistoric monuments in the surroundings, was declared a World Heritage Site by UNESCO in 1986. This type of construction is usually called “cromlech”, a term that comes from the old Welsh “crwnlech ”, that is, “flat stone (placed on) curve”. Worldwide, Stonehenge enjoys great popularity, attracting millions of visitors a year.

Stonehenge is made up of a series of rocks of different heights, arranged in four concentric circles. The row of rocks outside, have a measure of at least 30 meters high; Within this, there are other smaller rocks, which are distinguished by their blue color. In the middle of the monument, there is a large flat stone, which is always referred to as “The Altar”. Its construction is dated around 2500 BC, during the Neolithic; It was modified some time later, acquiring the current appearance. The methods used for its construction remain unknown, but the hypothesis that the stones were moved with wooden balls has gained great popularity.

The researcher from the University of Sheffield, the archaeologist Mike Parker Pearson, carried out a series of excavations in which he discovered an entire community, full of crags houses that were inhabited only at specific times of the year; thus, they began to speak of a great complex of cromlech and ceremonial avenues. However, regarding the purpose of Stonehenge, it has been argued that it could serve as an astronomical observatory or a kind of altar, to worship the corpses of important people; the first is supported by the Summer Solstice, since, during it, the sun rises through the axis of the construction and sets through the axis of Woodhenge, while the second is due to the discovery of the remains of 300 people, whose time of death agrees with that of the building.
