About Shiraz

Shiraz was a Persian capital and remains a city of gardens and poets, with the tomb of Hafez, the Eram Garden and the ornate Nasir al-Mulk Mosque among its landmarks. Persepolis and Naqsh-e Rostam, the Achaemenid ceremonial centre and royal tombs, lie about an hour away and make the obvious day trip. The Vakil bazaar and the old quarter are good for slow afternoons. March to May brings blossom and mild air, September and October are pleasant, and winter is cold but quiet.
