The Nadir Divanbegi Medressa was built as a caravanserai, but the khan thought it was a medressa and it dutifully became one in 1622. It's notable for its stunning exterior tilework, which depicts a pair of peacocks holding lambs either side of a sun with a human face, in direct contravention of the Islamic prohibition against depicting living creatures. Inside you'll find a few craft and carpet stalls.
