Bamiyan (also known as the buddha of bamiyan): these are two statues which were carved into a cliff around 3rd century A.D. The larger one is about 55m and the smaller one is about 38m. After being carved into the cliff, they were finished with fine plaster and decorated with gold and fine jewels; also, paintings were done all around these buddhas. Unfortunately, the town of Bamiyan, Afghanistan changed rulers multiple times and these statues were destroyed in 1221 by Mongol invader Genghis Khan. Then, in March of 2001, they were fully destroyed under command of the Afghan Taleban. People since have been attempting to dig out the statues in order to bring them back to have something to believe in again.
A picture on Dr. Karen Carr’s site shows of one of the two statues. They were used as a symbol of hope for monks who had traveled far and for the people who lived just off the valley of Bamiyan. The website is from: http://www.historyforkids.org/learn/centralasia/religion/index.htm
