Firozkoh

Firozkoh (Persian: فیروزکوه, Fīrōzkōh), or Turquoise Mountain, was the summer capital of the Ghurid dynasty, in the Ghor Province of central Afghanistan.

A historian of the dynasty, Minhaj al-Siraj Juzjani, wrote that the remaining citizens of Ghazna, imprisoned, were used to transport building supplies to Firozkoh.

In 1199, the Ghurid sultan, Ghiyath al-Din, ordered the empire to abandon the Karramiyya sect of Islam in favor of Shafi'i law.

[1] Firozkoh remained rich for a time—Juzjani wrote that the treasury contained "400 camel loads of gold in 800 chests"—although this claim may be unreliable.

[3] The primary contemporary source describing the history, layout, and buildings of Firozkoh is the Tabaqāt-i Nāsirī, written by Minhaj al-Siraj Juzjani.

When visited by Rory Stewart in 2002, the possible remains of the city had been heavily damaged by looters, and many of the treasures that were found had been sold in markets in Herat, Kabul, and Tehran.
