After making post about my olive trees in pots being still outside, I made some research on this subject. As result I found interesting blog about olives in general.
My search of oldest olive tree shows that it might be one in Zakynthos (Greece).
Crete also seems to be over 1000 years - but how much over?
In Portugal there is also one.
One info made me worried little bit. Global warming endangers olive grovs. According to Turkish Daily News due to lowering underground waters and sand coming from over Sahara, the harvesting this year was predicted decrease by 40%.
Interesting enough there is also news about growing olive trees commercially in UK, but also as decorative plant in the UK gardens.
