Personally, I think that it's really quite unbelievable that 3000+ years after Stonehenge was erected its purpose and its means of construction still remains something of a mystery.

To be sure - Stonehenge is an ancient monument that stands tall as one of the world's most awesome and curious treasures.

Built using precision measuring techniques, this structure continues to baffle modern-day archaeologists and historians, alike.

With some of the massive stones used to construct Stonehenge weighing up to 26 tons (and standing 18 feet tall and 7 feet wide), this huge megalithic structure will probably remain the mystery that it is now, and for time-eternal.
