Since Sāsānian times Yazd has been famous for beautiful silk textiles that were rivaled in later periods only by those of Kāshān and Eṣfahān. The city is still a major centre of silk weaving. It has spinning and weaving mills, a plant for the manufacture of water purification and filtration equipment, and considerable mining and quarrying activity; copper deposits nearby are processed at the Sar Cheshmeh facilities. Almonds, fruit, and some grain are grown near the city.
