Tous, Siraf & Persian Mosques Three New UNESCO World Heritage Candidates in Iran Three New UNESCO World Heritage Candidates in Iran: Tous, Siraf and the Persian Mosques Iran’s UNESCO World Heritage story is entering a new chapter. Following the inscription of Alamut Castle and its Related Fortifications on the UNESCO World Heritage List in July 2026, Iran now has 30 UNESCO World Heritage properties. At the same time, Iran is preparing several new nominations for possible future inscription. Among the most important are the historic city of Tous in Khorasan Razavi Province, the ancient port of Siraf on the Persian Gulf, and a serial nomination representing some of Iran’s most important historic mosques. These three candidates tell very different stories. Tous represents the cultural and literary heritage of Khorasan and the legacy of the great Persian poet Ferdowsi. Siraf recalls the extraordinary maritime trade that once connected Iran with India, China, East Africa and the wider Indian Ocean world. The Persian Mosque nomination, meanwhile, aims to demonstrate the long development of Iranian Islamic architecture across different historical periods and regions. For travelers interested in Iran’s history, culture, architecture and lesser-known heritage sites, these three places are especially worth watching. Iran Now Has 30 UNESCO World Heritage Sites. On July 26, 2026, Alamut Castle and its Related Fortifications were officially inscribed on the UNESCO World Heritage List during the 48th session of the World Heritage Committee in Busan, South Korea.

Iran Celebrates Its 30th World Heritage Site Alamut Castle and Its Historic Fortresses Inscribed on the UNESCO Iran has officially welcomed its 30th UNESCO World Heritage Site as the Alamut Castle and its Associated Fortifications. These were inscribed on the UNESCO World Heritage List during the 48th Session of the UNESCO World Heritage Committee held in Busan, South Korea. The newly inscribed building is not limited just to the famous Alamut Castle. UNESCO recognized a defensive network consisting of seven historic fortresses spread across the alleys of Eastern and Western Alamut in the Alborz Mountains. The property includes: Alamut Castle Lambsar Fortress Navizar Shah Fortress Shams Kalayeh Fortress Qostin Lar Fortress Shirkuh Fortress Ilan Fortress Together, these castles formed one of medieval Iran's most sophisticated mountain defense systems. Perched dramatically on a towering rocky cliff about 105 kilometers north of Qazvin, Alamut Castle overlooks deep valleys and rugged mountain landscapes. For nearly two centuries, from the late 11th century until the Mongol invasion in 1256, it served as the political, military, and intellectual center of the Nizari Ismaili state under Hasan-i Sabbah’s leadership. Apart from its reputation, Alamut was an extraordinary example of medieval engineering where archaeological studies highlighted its advanced water collection and storage systems. Its carefully designed fortifications, and strategic mountain architecture enabled the fortress to withstand long sieges. Historical records also describe Alamut as a center of scholarship, home to an important library and scientific activities. Rising above the cliffs, Alamut is far more than an ancient fortress. It is a symbol of resilience, strategic ingenuity, and one of Iran's most fascinating episodes of medieval history. For centuries, Alamut Castle has watched over the valleys of the Alborz, preserving stories that continue to inspire historians, archaeologists, and travelers from around the world.
