The Fin Garden (Bagh-e Fin), Kashan, is a walled Persian garden on the desert edge of Isfahan Province, central Iran, built around the Soleimaniyeh spring whose constant flow has supplied the basin since at least the Sasanian period. Its present layout dates to the Safavid reign of Shah Abbas I in the early 17th century, with major Qajar-era pavilions, painted ceilings, and the bathhouse added under Fath-Ali Shah and his successors. The garden is a textbook chahar bagh: cypress avenues quartered by stone water channels fed entirely by gravity from the spring, with turquoise-tiled basins, hundreds of small jet fountains driven by hydrostatic head alone, and a central kushk pavilion at the cross of the axes. Its bathhouse is the site where the Qajar prime minister Amir Kabir was assassinated on the orders of Naser al-Din Shah in January 1852, his veins opened in the cold room, which is preserved as a memorial. Fin was inscribed by UNESCO in 2011 as part of the Persian Garden serial property.
The Fin Garden fountains have run without pumps for four hundred years.
