Up to this day, Stonehenge in Britain remains one of the world's most iconic and mysterious locations. Built in three phases between 3,000 B.C. and 1,600 B.C., its purpose still eludes both researchers and the non-scientific alike. However, in light of the gathering at Stonehenge for the summer solstice, this year we might be one step closer to figuring out the purpose of Stonehenge.

Amidst the thousands of revelers, new-agers and self-styled Druids at Stonehenge to celebrate the summer solstice, was a man on a mission: Tim Daw, the steward at the site. Daw predicted that the midsummer sun would set in alignment with the back of the monument, according to The Huffington Post U.K.

Specifically, his theory involved a line of stones positioned at 80 degrees to the axis of the tallest stone, according to an interview with BBC.

Did his prediction hold?

Yes it did.

He stated: "[There was] a wonderful sunset last night. We could see the sun going down directly in line with...the back of the stone. It was fantastic."

While Daw tested his theory, about 23,000 sun-watchers gathered for the solstice, and according to police it was a peaceful event with only nine arrests for drug offenses - fewer than in the past.

With this mystery seemingly solved, it will be cool to see what predictions can be made about the rest of the site and to finally learn what its overall purpose might be.
