Nice commercial site about Stonehenge, complete with a timeline and some good photos.
From the site:
“There is no documented purpose for this monument but it has been referred to as a burial place, a calendar, and a place of worship and sacrifice. While new research has ruled out some earlier theories, there is still no solid confirmation on the original purpose of this monument. One thing is for sure, knowing the time period that this monument was built and the lack of technology puzzles the mind and creates a worldwide fascination. If you have plans to visit England, no visit is complete without a visit to Stonehenge. The construction and purpose of this monument are still unsure by researchers, but when you walk onto this ground, you will experience a step back in the past. Some visitors find the experience majestic, celestial, or spiritual when they first encounter Stonehenge.”
