Multan (مُلتان ; [mʊltaːn] (listen)) is a city in Punjab, Pakistan. Located on the banks of the Chenab River, Multan is Pakistan's 7th largest city, and is the major cultural and economic centre of southern Punjab. Multan's history stretches deep into antiquity. The ancient city was site of the renowned Multan Sun Temple, and was besieged by Alexander the Great during the Mallian Campaign. Multan was one of the most important trading centres of medieval Islamic India, and attracted a multitude of Sufi mystics in the 11th and 12th centuries, earning the city the nickname City of Saints. The city, along with the nearby city of Uch, is renowned for its large number of Sufi shrines dating from that era.
