2. The Largest Stones Weigh Around 25 Tons
The enormous outer stones, known as sarsens, can weigh up to 25 tons each.
These massive stones were transported from quarries about 20 miles away in the Marlborough Downs.
Moving stones of this size without modern machinery remains one of the greatest mysteries surrounding Stonehenge.

The smaller stones at Stonehenge, known as bluestones, were transported from the Preseli Hills in Wales, more than 150 miles away.
How prehistoric people moved these stones across such distances is still debated.
Some theories suggest they were transported by sledges and rollers, while others propose they were moved partly by water.
4. Stonehenge Was Built In Several Phases
Stonehenge was not built all at once.
Archaeologists believe construction took place in three main stages, beginning with a circular earthwork enclosure before the famous stone circle was added.

Archaeologists have discovered cremated human remains around the monument dating back thousands of years.
These discoveries suggest that Stonehenge may have originally served as an important prehistoric burial ground.
