Located three kilometers from the city of Razan near the village of Yangeh Qaleh, Imamzadeh Hood is a 12-sided structure with a dome in the form of a vault. Its history dates back to the Ilkhanate period. During its prosperous times, this building had a conical dome that has later collapsed. It was adorned with intricate and suspended brickwork and tilework in lapis lazuli, turquoise, white, and embellished with Kufic inscriptions. The building includes a basement beneath the floor of the shrine space, housing the main tomb. This structure was registered as a national heritage site on December 2, 1948, with the number 367.
