This Website from The Discovery Channel of Canada explores "some of the world's most enigmatic places." It features separate sections on three famous sites -- Easter Island, Nazca Lines, and Stonehenge -- discussing the construction, cultural significance, and physical history of the extraordinary structures erected at each. The site also offers a slideshow presenting dozens of dramatic photographs from the three places as well as links to pertinent news releases and features archived on the Discovery site. The discussions and images provided are extensive and can serve as a stand-alone source of information, suitable for individual or secondary education.
