sentences:  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.Although there are many sites in Kashan of potential interest to tourists, the city remains largely undeveloped in this sector, with fewer than a thousand foreign tourists per year.
