In one area of Spain, there's a place filled with Olive trees that have been around for a millennium. The Sea of Olives or Mar de Olivas, as they call it in Spain, has been greeting people who pass through it for thousands of years now. It's found in Southern Catalonia in the Montsià plains

The Sea of Olives rests between to mountain ranges just near the Ebro River and stretches for miles filling the valley. In fact, CNN reported that this location is where you can find the most number of millennial olive trees in the whole world.

An olive tree is considered millennial if it passes some standards. The trunk's diameter measured at a height of 1.3 meters from the ground should be at least 3.6 meters. Now, there have been 4,400 olive trees in the area registered as a millennial and there are still more out there that have not been located.

According to NewsFlog, most of the trees found in the area belong to the Farga variety. This kind of variety becomes less productive compared to others as time passes by so that's why most olive oil producers switched to other varieties. However, the Sea of Olives still stands and is being protected.

What's interesting is that there is actually a demand for the oil coming from these millennial olive trees of the Farga variety. Consumers all over the world are seeking for this new yet ancient taste of this oil.

The Farga de l'Arión, is the oldest olive tree in the Sea of Olives. Scientific research has proven that the tree is around 1,700 years old and it's is also suspected to be the oldest olive tree in the world according to Buzzbloggers.

According to the researchers at the Technical University of Madrid, the historical tree could date back as early as the fourth century. It's the time when Constantine the Great ruled Spain.

The Sea of Olives is not only rich with its 1000-year-old liquid gold but it's also rich with history. A lot of events took place in this area that the trees have witnessed all throughout the years.
