The Amir Chakhmaq Complex is a prominent structure in Yazd, Iran, noted for its symmetrical sunken alcoves. The mosque is located on a square of the same name, named after Amir Jalaleddin Chakhmaq, a governor of Yazd during the Timurid dynasty (15th-16th century CE). Architecture and fittings The prominent structure has a three-storey elaborate façade of symmetrical sunken arched alcoves. It is the largest structure in Iran. In the centre are two very tall minarets. The spiral staircase in one of the two minarets is said to create a feeling of claustrophobia, while it provides views of Yazd. At night, the building is lit up with orange lighting in the alcoves which makes it a spectacle. The complex also contains a caravanserail, a tekyeh, a bathhouse, a cold water well, and a confectionary. The bathhouse, in the front of the building is around 600 years old. Arcades have been added recently on the flanks to provide safety from traffic. Only the first floor above the ground level is accessible.
