Archaeologists have unlocked 5000-year-old secrets of "Scotland's Stonehenge" which reveal the extent of astronomical knowledge among the ancient site's builders. A groundbreaking 3D-laser scan of the renowned Callanish Stones on the Isle of Lewis has shown that the area's tribes were far more advanced than previously thought.The survey of the world-famous standing stones has demonstrated the great skill of the ancient architects and their understanding of astronomy and the environment. Archaeoptics, a team of scientists and archaeologists, conducted the digital scan, hailed as a major advance in archaeological techniques, which produced computerised three-dimensional images and analysis of the stones.The work will be used to produce educational material on the stones and shed light on their position within the greater Callanish complex and current archaeo-astronomical theories.Alastair Carty, of Archaeoptics, said: "This is the most accurate survey of the site carried out to date. "The technique is basically a device which measures 1000 points per second providing full 3D dimensions similar to existing surveying techniques but far, far more accurate. It also builds a dense 3D model. The model could be used to create virtual astronomical events. "We hope to help create a video or DVD that can add information about the stones through a fully interactive 3D model. As my equipment measures the area, an image builds up on the screen and you can immediately see what's going on." The site dates from roughly 3000 BC, but precise dates and proven functions have been hard to establish. Standing on a hill overlooking Loch Roag, the enigmatic monument seems to have been aligned with various large stars, and the sun and the moon, as well as distinctive points on the horizon.

Thirteen tall stones, made from the local metamorphic rock, surround a stone burial tomb. A nearly-parallel avenue of 19 stones leads up to the circle and beyond, with two other arms leading to the west and east. From above, the Callanish resembles a Celtic cross. Mr Carty said: "Callanish is one of the most important and best preserved stone rings in Scotland and many would argue that it is even more evocative than Stonehenge. "This work showed how much the builders were in tune with their environment. It was amazing to get an insight into the mindset of the site's architects."Many of the great monuments and ceremonial constructions of early civilisations were astronomically aligned. The precise orientation of the Great Pyramid at Giza in Egypt or the Venus alignment of the Maya Palace of the governor at Uxmal in Yucatan are outstanding examples.

i've heard lots and lots of stories about these stones. my most favorite (which seems more believable) is the one where the holes were dugged out and then the rocks were simply slided in and then the sand was removed leaving the stones standing. pretty neat huh?
but i do like to be surpraised!
