Stonehenge is a prehistoric monument located in the English county of Wiltshire, about 3.2 kilometres (2.0 mi) west of Amesbury and 13 kilometres (8.1 mi) north of Salisbury. One of the most famous prehistoric sites in the world, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones. Archaeologists had believed that the iconic stone monument was erected around 2500 BC, as described in the chronology below. However one recent theory has suggested that the first stones were not erected until 2400-2200 BC, whilst another suggests that bluestones may have been erected at the site as early as 3000 BC (see phase 1 below). The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. The site and its surroundings were added to the UNESCO's list of World Heritage Sites in 1986 in a co-listing with Avebury henge monument, and it is also a legally protected Scheduled Ancient Monument. Stonehenge itself is owned by the Crown and managed by English Heritage while the surrounding land is owned by the National Trust. http://en.wikipedia.org/wiki/Stonehenge If you were looking for a "little green men from outer space" connection, I am not a good source of such silliness.

Well, these two druids decided to set up a chain of really big dominoes but a few of them didn't fall.

It was my husbands failed attempt at decorating his parents house when he was a kid.

There is all sorts of speculation, but nobody knows, in the same way that nobody knows what purpose it may have served.

apparently there is an ancient carving of an alien on one of the columns does this give you an idea of its use
