The small, fifth-century Sasanian building east of Sarvestan (satellite photo) is usually called a palace, but no one knows what the building really is. It may have been a hunting lodge or a religious site; but it may as well have been a palace, because it resembles the Qalah-e Dokhtar and the palace of Ardašir at Firuzabad. Whatever the function of the ruin near Sarvestan, it is well-preserved, and worth a visit. It will take an afternoon, if you rent a car in Shiraz. And if you don’t like to go to Iran, your photos are here.
