Deir Hanna
Throughout Israel and Palestine, dozens of ancient olive trees are found with estimated ages of 1,600–2,000 years; however, these estimates could not be supported by current scientific practices. Ancient trees include two giant olive trees in Arraba and five trees in Deir Hanna, both in the Galilee region, which have been determined to be over 3,000 years old, although no available data support the credibility of the study that produced these age estimates, and as such, the 3000 years age estimate can not be considered valid. All seven trees continue to produce olives.
