The Amir Chakhmaq Complex (Persian: مجموعه میدان امیرچخماق‎, romanized: Majmūʿa Meydân Amir Čaqmaq; also Romanized Chakhmaq, Chakmaq, Chakhmagh, Chakmak) is a prominent structure in Yazd, Iran, noted for its symmetrical sunken alcoves. It is a mosque located on a square of the same name. It also contains a caravanserai, a tekyeh, a bathhouse, a cold water well, and a confectionery. At night, the building is lit up after twilight hours after sun set with orange lighting in the arched alcoves which makes it a spectacle. During the Iran–Iraq War and the Iraq wars with the United States and Afghanistan, many Iraqis and Afghanis came to inhabit the Amir Chakhmaq Square.
