The Sisters Olive Trees of Noah are a grove of sixteen olive trees in the Lebanese town of Bcheale.
[2][3] However in 2024 a study using carbon dating found the oldest tree to be only 1,162 years old, plus or minus 131 years.
This makes it the oldest known olive tree in the world.
[4] Folk legend also ascribes The Sisters as the source of the olive branch returned to Noah's Ark at the waning of the Biblical Flood.
[5][6] The trees still produce olives, and a preservation effort was undertaken by the non-profit organization Sisters Olive Oil, which marketed oil from these olives.
