Underground Mill Tour and Olive Oil Tasting near Alberobello and Ostuni
Descend into a medieval frantoio ipogeo and discover the ancient art of olive oil making in the heart of the Valle d'Itria.
Just steps from Martina Franca's historic center, between the iconic landscapes of Puglia olive oil tasting country, a medieval underground mill carved into the rock reveals a world where centuries of tradition are preserved in stone, scent, and flavor.
The frantoio ipogeo was once the operational heart of an entire economy, producing olio lampante, the oil that lit homes and fueled commerce across the region for generations. Workers known as trappitari lived below ground from November through May, guided by a nachiro and aided by blindfolded mules turning massive grindstones in the cool, darkened chambers.
Today, that same underground space offers visitors an encounter with living history. Original machinery, olive storage niches, animal stalls, and ancient cisterns remain largely intact, forming a rare and tangible record of agricultural life in southern Italy from medieval times through the modern era.
