Shiraz is a city in south-central Iran, known for its literary history and many gardens. The marble Tomb of Hafez, honoring the revered poet, sits within its own garden. To the east, the Mausoleum of Saadi houses the 13th-century writer’s mosaic-tiled tomb and an underground pool. Shiraz is a gateway to Persepolis, the ruined 6th-century-B.C. capital to the northeast, with its immense gateways, columns and friezes.
