2Stonehenge, Wiltshire, England

This prehistoric monument dates from between 3000 B.C.E. and 2000 B.C.E. and is one of the United Kingdom’s most famous ancient sites.

This iconic ring of standing stones lies in the middle of a much larger archaeological site near Amesbury. It includes literally hundreds of burial mounds and other “henges,” like Avebury Henge and Woodhenge.
