Shiraz is said to be the city of some of the finest of life’s expressions and pleasures- wine, with the French naming a dry red wine after the city; flowers, gardens, the nightingale bird who flies above; and literature and poets.  Shiraz was the birthplace and is now the resting place, with two monuments in the city, of the great Persian poets Hafez and Saadi. One is dedicated to Sa'adi, the author of the famous Golestan, a book of sonnets called the Garden of Roses.

The other, pictured, belongs to Hafez.  Hafez was the master of Persian lyrical poetry whose works can be found in almost all traditional homes of the country. He famously influenced Iranian composers, was said to have "laughed the joys of love and wine but also targeted religious hypocrisy,” is culturally received to have memorized the works of poet, mystic, Islamic scholar, and lyricist Rumi amongst others, and most notably, the Quran at an early age.

Twenty years after his death, while phenomena and mysteries entwined his enlightened life and culturally mourned death, a tomb, the Hafezieh, was erected to honor Hafez in the Musalla Gardens in Shiraz, designed by André Godard, a French archeologist and architect. In the late 1930s, the tomb was raised up among blossoming roses and orange trees, and canals were created in the garden. His tomb is "crowded with devotees" who visit the site in a jovial air-singing and reciting chosen works from Hafez, the most popular poet in all of Iran.
