The Olive Tree
Few plants have shaped human civilization as quietly and as profoundly as the olive tree. Long before written language existed in any form we would recognize, people were cultivating Olea europaea – pressing its fruit for oil, burning that oil for light, trading it as currency, and weaving it into the rituals of birth, death, victory, and worship.
The true origin of olive cultivation remains contested. Some place it on the Greek island of Crete around 5,000 BC; others point to Syria, Iran, and the Palestinian region. What is certain is that ancient Syrian documents from around 2,000 BC already speak of olive oil as something precious – a symbol of peace, wisdom, and prosperity that carried meaning far beyond its practical uses.
A Tree That Built Civilizations
Every major civilization that touched the Mediterranean carried the olive with them. The Egyptians, Phoenicians, Greeks, and Romans spread its cultivation along the coastlines of Southern Europe and North Africa over centuries of trade, conquest, and cultural exchange. The result is a geographical concentration that remains extraordinary to this day: 97 percent of all olive trees in the world are found in the Mediterranean region.
In Greek mythology, the olive was a divine gift. When Athena and Poseidon competed for supremacy over Attica, Athena offered the people an olive tree – planted, according to tradition, on the rocky hilltop now known as the Acropolis of Athens. The tree standing there today is said to be descended from that very first one. Whether myth or memory, the story captures something true about how central the olive has always been to Greek identity and culture.
The Greeks anointed Olympic victors with olive oil. Other cultures used it to honor their dead. The Christian church, alongside many other religions, still uses it to mark sacred occasions. Few plants have carried so much symbolic weight across so many different traditions.

A Living Ancient
Olive trees are among the longest-lived cultivated plants on earth. Trees more than a thousand years old still bear fruit in Sardinia, mainland Greece, and Macedonia. The oldest known specimen, on Crete, is estimated to be around 4,000 years old – still producing olives, still standing.
Their extraordinary longevity owes much to the Mediterranean climate itself: temperate winters, dry summers, and well-drained soils that have supported more than 100 distinct varieties across the region. Each variety carries its own character – different flavor profiles, different oil compositions, different relationships to the land they grow in.
It takes between 10 and 15 years for a newly planted olive tree to reach full production – a reminder that olive growing has always required patience, a long view, and a willingness to tend something whose full benefit you may not live to see in its entirety.
From Ancient Grove to Modern Production
Traditionally, olives are harvested by hand in autumn and winter – a slow, labor-intensive process that connects growers to their trees in a way that mechanization struggles to replicate. Long poles are used to beat the fruit loose; nets spread beneath the branches catch what falls. In many parts of the Mediterranean, this is still how it’s done.
But the economics of modern production have shifted the landscape considerably. Where traditional groves planted trees 7.5 meters apart – around 70 per hectare – modern high-density farming plants between 250 and 900 trees per hectare, with mechanical harvesting dramatically reducing labor costs and time.
Spain now leads global olive oil production, accounting for roughly a third of the world’s supply. Italy follows, then Greece, Morocco, and Turkey. Around 90 percent of the olive harvest is pressed into oil; the remainder is cured and sold as table olives. The hard, dense wood of the olive tree – beautiful and extraordinarily durable – is also prized for furniture, wind instruments, and handcrafted utensils.

A Tree That Endures
There is something quietly remarkable about a crop that has been continuously cultivated for at least 7,000 years – through the rise and fall of empires, through wars and famines and radical transformations of the landscape – and that remains, today, as central to Mediterranean life and health as it has ever been. The olive tree doesn’t hurry. It doesn’t need much. It simply endures – and rewards, generously, those who tend it with patience.
