Stonehenge is a complex of menhirs and stone circles, located on the Salisbury Plain about 13 km north of Salisbury in Wiltshire, southern England.
Stonehenge is Britain's largest monument and the most famous remnant of the Bronze Age. For years, it was considered a temple of the sun, an astronomical calendar, or a shrine of the dead ancestors. There are a number of theories, including that Stonehenge was a place of worship for druids, Celtic priests. According to scientists, it is more meaningful to assume that rather than a place for worship, observation of natural phenomena or healing of ailments, this monument should serve as a building for meeting people.

Archaeological research in 2008 revealed that for 7,000 years BC collectors and hunters lived on the site, who also built wooden buildings.

The oldest is a circle with a diameter of 110 m from the outside of the moat and the inside of the rampart; was built around 3100 BC. The Val was only 0.5 m high. The ditch was 2 m deep and bones of game and cattle were placed at its bottom to consolidate the soil.

The oldest - dolerite - stone circle was erected around 2.300 BC.

It is not a unique building (some center of a larger area). Based on the mapping of the Stonehenge surroundings, archaeologists have found that at least 17 other shrines were located around Stonehenge.
