It's not an easy question to answer, not directly that is. What is for sure is that our interpretations of its 'purpose' are very likely to be wrong, for example there is not scrap of archaeological evidence that Stonehenge ever functioned as 'an observatory' that is a modern myth. That said it has an axis of alignment fixed on the shortest and longest days of the year (the winter and summer solstices). If we are to get near to understanding its purpose we need to know what went into its design, and that can be answered.
If we look closely we see a geometrically accurate piece of architecture, one that is designed precisely around mirrored symmetry (set either side of the axis). 'Astronomical' events tend not to be 'symmetrical' when translated into features and the ground, and such alignments that exist are to be found between the stones themselves , not to distant objects or sight lines. In short Stonehenge was designed on a drawing board, largely prefabricated, and somehow reflects a prehistoric cosmology, a religion - that was concerned with harmonious mirrored symmetry.
Because the people who built Stonehenge left no written records, the purpose of its construction is still a matter of debate. Some have suggested Stonehenge may be a burial ground, while others believe it was a place of healing
It became a mystery as soon as people forgot the purpose for which it was built.
Stonehenge is thought to have been built by the beaker people.
People
Stonehenge is not a natural formation, it was built by people.

Stonehenge was first seen by the ancient people who built it.
No it was not built by Egyptians
Not century but millennium. Stonehenge was built around 5000 years ago, but nobody knows for absolute certainty.

The major stones of Stonehenge are mostly sandstone, others are igneous rocks.
Not At All! It Was Built In 5000 BCE.
