Stonehenge

Stonehenge was built, or rather the process of Stonehenge, began over 10,000 years ago. We're talking 8,000 BC people. over thousands of years, entire cultures used the area for a myriad of suggested purposes, and morphed the landscape into what we see today.

4,000 years ago, enormous rocks, each weighing about 25 tonnes, were moved from an area 24 miles away to its current site and propped rigorously into vertical, perfectly circular positions. more rocks of equal size and weight were then hoisted on top of these vertical rocks and dove tailed into the standing rocks. and this is no mean feat. these rocks are standing on uneven ground and yet strangely all but one of the horizontal rocks sits flat at equal height.

and to this day, we still haven't quite figured out how they did that! who are we to think we're now so much smarter than our ancestors...
