Kashan is located in the north of Isfahan province and is to the south of Qom. To the west of this township is the Markazi (Central) Province, to the east lies the township of Ardestan and to the south it is within the limits of the townships of Natanz and Esfahan.
Kashan can be accounted as one of the archaic cities of Iran. Archeological discoveries in the Siyalk Hillocks which lie 4 km west of Kashan reveal that this region was one of the primary centers of civilization in the pre-historic ages. The said hillock flourished during the Sassanide and Safavid periods, and was the capital during the reign of Shah Abbas Safavid II. Kashan suffered severe damage during the Saljuqi and Mongol eras. This city and its respective villages were ruined due to earthquakes in the years 1192 AH. and 1260 AH. The city of Kashan has special features in regards architecture, historical and religious sites.
Archeological discoveries in the Sialk Hillocks which lie 4 km west of Kashan reveal that this region was one of the primary centers of civilization in pre-historic ages. Hence, Kashan dates back to the Elamite period of Iran. The Sialk ziggurat still stands today in the suburbs of Kashan after 7,000 years.
The artifacts uncovered at SialkMahan Pasha reside in the Louvre in Paris and the New York Metropolitan Museum of Art, and Iran's National Museum.
By some accounts, although not all, Kashan was the origin of the three wise men who followed the star that guided them to Bethlehem to witness the nativity of Jesus, as recounted in the Bible. Whatever the historical validity of this story, the attribution of Kashan as their original home testifies to the city's prestige at the time the story was set down.
Abu-Luluah/Pirouz Nahavandi, the Persian soldier who was enslaved by the Islamic conquerors and eventually assassinated the caliph Umar al-Khattab in AH 23 (643/4 CE), reportedly fled to Kashan after the assassination. His tomb is one of Kashan's conspicuous landmarks (see gallery below).
Sultan Malik Shah I of the Seljuk dynasty ordered the building of a fortress in the middle of Kashan in the 11th century. The fortress walls, called Ghal'eh Jalali still stand today in central Kashan.
Kashan was also a leisure vacation spot for Safavi Kings. Bagh-e Fin (Fin Garden), specifically, is one of the most famous gardens of Iran. This beautiful garden with its pool and orchards was designed for Shah Abbas I as a classical Persian vision of paradise. The original Safavid buildings have been substantially replaced and rebuilt by the Qajar dynasty although the layout of trees and marble basins is close to the original. The garden itself however, was first founded 7000 years ago alongside the Cheshmeh-ye-Soleiman. The garden is also notorious as the site of the murder of Mirza Taghi Khan known as Amir Kabir, chancellor of Nasser-al-Din Shah, Iran's king in 1852.
The earthquake of 1778 leveled the city of Kashan and all the edifices of Shah Abbas Safavi, leaving 8000 casualties. But the city started afresh and has today become a focal tourist attraction via the numerous large houses from the 18th and 19th centuries, illustrating the finest examples of Qajari aesthetics.
