The Amir Chakhmaq Complex is a historical site located in the city of Yazd, Iran. The complex includes a mosque, a caravanserai, a bathhouse, a cold water well, and a bazaar. It was built in the 15th century during the Timurid dynasty and later underwent several renovations during the Safavid era.

The complex is named after Amir Jalal al-Din Chakhmaq, who was a governor of Yazd during the Timurid era. The most distinctive feature of the complex is its façade, which has three floors of symmetrical, arched alcoves that provide shade and cooling during the hot Yazd summers. The façade is adorned with intricate geometric patterns and tilework that showcase the region's traditional architecture.

The mosque of the Amir Chakhmaq Complex is located behind the façade and features a large prayer hall with several iwans, or vaulted halls. The caravanserai and bathhouse are located to the east and west of the mosque, respectively. The cold water well, which was used for storing ice and keeping perishable foods cool, is located on the north side of the complex. The bazaar, which is still active today, is located to the south of the complex and features shops selling traditional goods, handicrafts, and souvenirs.

The Amir Chakhmaq Complex is a popular tourist attraction in Yazd and has been recognized as a UNESCO World Heritage Site. It is a testament to the city's rich cultural and architectural heritage and provides a glimpse into the daily life of people in the region throughout history.
