List of Assassin strongholds

List of the strongholds or dar al-hijra of the Order of Assassins in Persia (Iran) and Syria.

Most of the Persian Ismaili castles were in the Alborz mountains, in the regions of Daylaman (particularly, in Alamut and Rudbar; north of modern-day Qazvin) and Quhistan (south of Khurasan), as well as in Qumis.

According to Juzjani, before the Mongol invasion the Assassins possessed 70 forts in Quhistan and 35 in Alamut.

[2] The Ismaili fortresses in Rudbar of Alamut had been built on rocky heights and were equipped to withstand long sieges; they had storehouses with high capacities and elaborate water supply infrastructure such as cisterns, qanats, and canals.

[3] The strongholds in Jabal Bahra' were known as the "Castles of the da'wa" (قلاع الدعوة qilāʿ al-daʿwah).
