Fin Garden is a historic Persian garden located in Kashan, Iran. It contains Kashan’s Fin Bathhouse, where Amir Kabir, the Qajar era chancellor, was assassinated by the order of Naser al-Din Shah Qajar in 1852. Completed in 1590, the Fin Garden is the oldest extant garden in Iran.

History
The origins of the garden may be anterior to the Safavid era; some sources indicate that the garden has been relocated from another place, but no clear picture of it has been found.
The settlements of the garden in its present form was built during the reign of Abbas the Great (r. 1587–1629), as a traditional bagh near the village of Fin, located a few kilometres southwest of Kashan.

The garden subsequently suffered from neglect and was damaged several times until, in 1935, it was listed as a national property of Iran.UNESCO declared the garden a World Heritage Site on 18 July 2012.

Fin Bathhouse is a “bath museum” in Fin garden, Kashan. It is the location of Amir Kabir’s assassination on 10 January 1852. This bathhouse consists of one large and one small bath.
The construction of a small bath is related to the Safavid era and has been created with the original garden building. By building a large bath in the time of Fath Ali Shah, the large bath was allocated to state dignitaries, becoming known as the Royal Bath. In contrast, the small bath was used by the general population. Remarkably, both baths had all the traditional features and architectural elements of an Iranian bathhouse. In 1314 HS, the Fin Bathhouse was registered as a national monument and in 2011, it was registered in the UNESCO World Heritage List.
