Astarabad
Astarabad is the older name of the city of Gorgan, southeast of the Caspian Sea in northern Iran (the name was officially changed to Gorgan in the 20th century). It was a medieval centre of learning; the philosopher-theologian al-Sharif al-Jurjani (d. 1413) took the nisba al-Astarabadi/al-Jurjani from this region.
