(CNN)It’s a sight that’s been greeting travelers for thousands of years.
On the Montsi plains of southern Catalonia, about a two-hour drive south of Barcelona, lies the Mar de Olivas, or Sea of Olives.
Here, shielded between two small mountain ranges, in a broad dry valley near the mouth of the Ebro River, olive groves stretch as far as the eye can see.
And not just any olive trees: This area hosts the largest concentration of millenary olive trees anywhere in the world.
To qualify as one of these ancient olive trees, the diameter of the trunk has to be more than 3.5 meters, measured at a height of 1.3 meters from the ground.
More than 4,400 trees thought to be 1,000 years or older have already been located and cataloged, while many more may be waiting to be discovered.
With most of these trees still producing oil, customers worldwide are developing a new taste for this ancient flavor.
The oldest olive tree in the world
Those looking for even older artifacts can’t miss the cave paintings at nearby Serra de Godall.
Here, some 8,000 years ago, groups of huntsmen left their pictorial mark in a series of open rock shelters.
The amazing hunting scenes, one of the few sites in Mediterranean cave art to feature women, are clearly visible to the naked eye and accessible for close-up inspection.
As you can see, even the oldest of the trees can look young next to some of the heritage surrounding them.
By claiming back their ancient olive trees, though, the inhabitants of this little-visited corner of the Mediterranean are not only tapping a sustainable economic resource, but re-establishing a direct link with this remote past.
