Tomb of Hafiz, the celebrated Iranian poet
This is the tomb of Hafiz, a celebrated Iranian poet. His full name was Khaje Shams ud-Din Hafiz-i Shirazi, and he lived from 1326-1390.
After the Holy Koran and Islamic prayer books, Hafiz's collection of poems is probably the most popular book in Iran. (I can hardly imagine an Iranian household not having a copy, so you can guess how popular he is!)
