Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, two miles (3 km) west of Amesbury.It consists of an outer ring of vertical sarsen standing stones, each around 13 feet (4.0 m) high, seven feet (2.1 m) wide, and weighing around 25 tons, topped by connecting horizontal lintel stones, held in place with mortise and tenon joints, a feature unique among ...
Construction on Stonehenge began as early as 3000 BC and occurred over several phases in an area first inhabited as early as 5,000 to 6,000 years ago, according to the researchers.
The various parts of Stonehenge 3 may have involved up to 1.75 million hours (73,000 days or 200 years) of work. The working of the stones is estimated to have required around 20 million hours (830,000 days or 2,300 years) of work using the primitive tools available at the time.
Stonehenge was likely built as a project to unify ancient peoples from across the whole of the country, archaeologists claim in a new study.. More than 900 stone circles have been discovered ...
The Summary. The "altar stone" at the center of Stonehenge likely originated in present-day Scotland, a study found. That's more than 450 miles away, raising questions about how ...
By the time the standing stones of Stonehenge 3 were erected (around 2600 BC), the holes had fallen out of use. The positions of the holes are marked at the Stonehenge site by white discs laid in the ground surface. Archaeologists number them 1 to 56 counting clockwise from the later Slaughter Stone at the eastern side of the north east entrance.
Stonehenge's latitude ( 51° 10′ 44″ N ) is unusual in that only at this approximate latitude (within about 50 km) do the lunar and solar alignments mentioned above occur at right angles to one another. More than 50 km north or south of the latitude of Stonehenge, the station stones could not be set out as a rectangle.
But in a surprising twist, a new analysis suggests that the stone didn’t originate from Orkney, an archipelago off Scotland’s northeastern coast that’s home to 5,000-year-old Neolithic sites.
