Islamic conquerors and who eventually assassinated the caliph Umar ibn al-Khattab in 644, fled to Kashan after the assassination. The shrine that was built over his supposed tomb is one of Kashan's notable landmarks. 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 in 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 7,000 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 8,000 casualties. But the city started afresh and has today become a focal tourist attraction due to the numerous large houses from the 18th and 19th centuries, illustrating the finest examples of Qajari aesthetics.
