The three Greek places mapped here answer the age question in different ways. We map 20 trees in 3 cities here. The oldest of them is The Olive Tree of Azoria (Kavousi) in Crete, at roughly 3,000 to 3,400 years.
Thessaloniki took core samples from four plane trees in 2019: 828 years for the one below the Byzantine walls, then 310, 235 and 205 for the others. Athens works in inheritance: the olive beside the Erechtheion is tied by Herodotus to the Persian sack of 480 BC, though the wood standing today is only 70 to 110 years old, since an olive regrows from its base and a trunk is never the tree's age. Another Athens olive carries an estimate spanning 300 to 2,500 years. Crete claims outright: the Olive Tree of Vouves is put at 2,000 to 4,000 years and still bears fruit, and a second, at Azoria, carries 3,000 to 3,400 years from pottery buried in its roots. All three say so plainly, which is more than most places manage. Twenty trees so far.
