Fīrūzkūh
Firuzkuh, the summer capital of the Ghurid rulers, lay among the mountains of Ghor. The remains at Jam, where the Hari Rud meets the Jam Rud, are widely identified with it. There Sultan Ghiyath al-Din raised a tall brick minaret in the late twelfth century. Its intricate inscriptions and decoration testify to the Ghurids, whose power reached from the Afghan highlands into northern India.
