The website for the National Gallery of Art exhibition - Afghanistan: Hidden Treasures from the National Museum, Kabul - primarily consists of an interactive timeline of artifacts from Afghanistan dating from the Bronze Age, 2200 - 1900 B.C. through the 2nd century A.D. For example, view gold bowls from Tepe Fullol, a site discovered in 1966, providing the first evidence of Bronze Age Culture in northern Afghanistan; or a gilded silver ceremonial plate from the former Greek city of A" Khanum, founded by a follower of Alexander the Great in 300 B.C. The purpose of the exhibition is not only to showcase, but also to preserve, the rich but endangered history and culture of Afghanistan. In ancient times a crossroads of the Silk Road, Afghanistan in the 20th and 21st centuries has been ravaged by wars and conflict. Visitors should also check out the link "History and Maps", which leads to more information from the National Geographic Society, a co-organizer of the exhibition.
