Niasar Fire Temple

The Niasar Fire Temple, also known as the Niasar Chahartaqi, is one of the outstanding monuments of the Sassanian era. It stands in the Karkas heights, near the town of Niasar and 25 kilometers west of Kashan. The building was registered on the list of Iran's National Heritage in 1317 (Solar Hijri) under registration number 316, and it is regarded as one of the best-preserved and most beautiful chahartaqis surviving from the Sassanian period.

The Niasar Fire Temple was built during the reign of Ardashir I (Ardashir Babakan), founder of the Sassanian dynasty, and is of particular importance as the first temple and fire temple built at the height of the spread of the Zoroastrian religion in Iran. The structure is made of sedimentary stone and gypsum mortar, and has an egg-shaped dome resting on a square chahartaqi base measuring roughly 14 by 14 meters. This design demonstrates the skill of Sassanian architects in building durable and elegant domes. The Niasar spring near the building played an important role in the life of local people, bringing prosperity and supporting agriculture and orchards. These climatic conditions once made the site an ideal place for holding religious ceremonies and keeping the sacred fire.

The route is suitable for walking, and along the way you can enjoy beautiful natural views of the Karkas Mountains and the surrounding plains.
