The Cypress of Abarkuh (Persian: سرو ابرکوه‎‎ Sarv-e Abarkuh), also called the Zoroastrian Sarv, is a Cupressus sempervirens tree in Abarkuh in Yazd Province of Iran. It is protected by the Cultural Heritage Organization of Iran as a national natural monument and is indeed a major tourist attraction with a height of 25 metres and circumference of 18 metres. It is estimated to be over four millennia old and is likely the second-oldest living thing in Asia. The next oldest tree of its type is the 4,845-year-old bristlecone pine (Pinus longaeva) in the Great Basin of California. Although not named or officiated, another bristlecone pine also in the Great Basin of California was announced to be 5,062-years-old.
