What it is Filled
A square building of four arches supporting a dome, a form of Iranian architecture used for Zoroastrian fire temples in the Sasanian period and adopted in Islamic architecture for mosques, mausoleums and pavilions; the name means four arches in Persian, and surviving examples such as the chahartaq at Niasar and Natanz show the form that influenced the domed chamber across the Islamic world.
