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 with a perimeter of 11.5 meters at its trunk and 18 meters higher up around its branches. It is estimated to be over four millennia old and is likely the oldest or second-oldest living lifeform in Asia.
The exact age of the tree has been difficult to determine, but it is estimated to be between 4000 to 5000 years old. Favorable natural conditions of its location have been credited as the main reason for the tree’s longevity.[who?]
