857-33936 - A man feeds white doves at dawn in front of the Blue Mosque, Mazar-i-Sharif, Balkh Province. Hundreds of doves, who are fed by worshippers and tended by special workers, live around the mosque, and it is thought that the place is so holy that a grey or brown dove will turn white if it lands on the Mosque. The mosque is also known as the Shrine of Hazrat Ali (Hazrat Ali was the son-in-law of the prophet Mohammed), who is believed to be buried here. The shrine, of particular importance for Afghanistan's Shi'ite Muslims, was first built in the 12th century, destroyed by Genghis Khan, and rebuilt in 1481. The current mosque, considered by some to be one of the most beautiful in Central Asia, is a modern restoration.
