Fin Garden, or Bagh-e Fin, located in Kashan, Iran, is a historical Persian garden. It contains Kashan's Fin Bath, where Amir Kabir, the Qajarid chancellor, was murdered by an assassin sent by King Nasereddin Shah in 1852. Completed in 1590, the Fin Garden is the oldest extant garden in Iran.
The garden covers 2.3 hectares with a main yard surrounded by ramparts with four circular towers. In keeping with many of the Persian gardens of this era, the Fin Garden employs a great many water features.
These were fed from a spring on a hillside behind the garden, and the water pressure was such that a large number of circulating pools and fountains could be constructed without the need for mechanical pumps.
The garden contains numerous cypress trees and combines architectural features of the Safavid, Zandiyeh and Qajar periods.
In 1935, Fin Garden was listed as a national property of Iran. In September 2007, Bagh-e Fin was submitted to the UNESCO's Tentative List. Unesco declared the garden a World Heritage Site on July 18, 2012.
