The region now known as Andalusia became a major supplier of olive oil across the Roman Empire. Spanish olive oil traveled through Europe and North Africa in clay amphorae shipped from Roman ports.

Archaeologists have even discovered evidence in Rome itself. A famous artificial hill called Monte Testaccio was formed largely from broken amphorae that once carried olive oil from Spain.

The Moorish Influence That Changed Spanish Agriculture

Centuries later, the Moors arrived in the Iberian Peninsula and revolutionized agriculture throughout Spain.

They introduced:

• Advanced irrigation systems
• Water channels and reservoirs
• Sophisticated farming methods
• Improved olive cultivation techniques

Even the Spanish word for olive oil — aceite — comes from the Arabic word az-zait, meaning “olive juice.”

Their influence remains deeply visible in southern Spain today, especially throughout Andalusia, where olive groves stretch endlessly across rolling hills.

Some olive trees in Spain are believed to be hundreds, even thousands, of years old.

These trees are not only agricultural treasures — they are living witnesses to Spanish history.
