Detailed explanation-1: -Built in several stages, Stonehenge began about 5, 000 years ago as a simple earthwork enclosure where prehistoric people buried their cremated dead. The stone circle was erected in the centre of the monument in the late Neolithic period, around 2500 BC.

Detailed explanation-2: -In 1963 American astronomer Gerald Hawkins proposed that Stonehenge had been constructed as a “computer” to predict lunar and solar eclipses; other scientists also attributed astronomical capabilities to the monument. Most of these speculations, too, have been rejected by experts.

Detailed explanation-3: -Stonehenge’s outer ring consists of sarsen sandstone slabs that hail from local quarries, but its inner ring is made up of smaller rocks called bluestones that scientists have traced to the Preseli Hills in Wales, some 200 miles from where Stonehenge sits on England’s Salisbury Plain.

Detailed explanation-4: -When was Stonehenge built? Work started on this super stone circle around 5, 000 years ago in the late Neolithic Age – but it took over 1, 000 years to build, in four long stages! Archaeologists believe the final changes were made around 1, 500BC, in the early Bronze Age.
