Shiraz, celebrated for more than 2,000 years as the heartland of Persian culture, is known as the home of Iranian poetry and for its progressive attitudes and tolerance. Like all of Iran, this week Shiraz observes the 25th anniversary of the death and continued legacy of the Ayatollah Khomeini, the father of the Islamic revolution. By John Moore/Getty Images.
