Kashan in central Iran, ( with pop more than 500,000 / elev 935m ) and its surrounds have been home to human settlements since at least the 4th millennium BC. During the Seljuk period (AD 1051-1220) it became famous for its textiles, pottery and tiles. Much of Kashan was destroyed by an earthquake in 1779 but the subsequent Qajar period saw building on a lavish scale. The most notable survivors are Fin garden, Aqa-bozorg mosque , the fine covered bazaar with arcades and several meticulously restored mansions. Hiding behind the high mud-brick walls of Kashan are hundreds of traditional houses, built during the 19th century. Those like Ameri, Tabatabai, Borujerdi, Abbasian, Taaj and etc that can be visited are monuments to the importance of Kashan as a Qajar- era carpet commercial hub.
Now also kashan every April & Mey attracts many groups of Iranian and foreigners because of the festival of rose water.
There are many large and small industries in Kashan that every year export a lot of goods like machine carpets, rosewaters, herbal products and etc to the foreigner countries.
