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.

In 1901 in a restoration which caused outrage at the time but which is rarely referred to in official guidebooks. For it means that Stonehenge, jewel in the crown of Britain's heritage industry, is not all it seems. Much of what the ancient site's millions of visitors see in fact dates back less than 65 years.

From 1901 to 1964, the majority of the stone circle was restored in a series of makeovers which have left it, in the words of one archaeologist, as 'a product of the 20th century heritage industry'. But the information is markedly absent from documentaries like this one, the guidebooks and info-phones used by tourists at the site.

Well-done documentary that introduces some new facts about the archeology of Stonehenge, or at least ones I was not familiar with.

Be cautioned that this program does play like an educational documentary, and it may be hard to get children and some adults to sit still for it.

The featured archaeologist weaves an interesting story about what he believes Stonehenge represented to the people who built it, and he does muster new evidence to support his suppositions, but his story is still far from completely convincing. In no way at all do I feel that Stonehenge has been conclusively "decoded," and the frequent comments about how this or that is now proved were annoying.

Still, it was an interesting show with some valuable insights into one of the world's most famous mysterious monuments.
