Apulia has a high number of underground oil mills dug into the rock, these are ancient oil industries. Today, most of these are abandoned. Millenari di Puglia has identified the most fashionable and beautiful underground oil mills and provides a facility for them to be visited in the company of one of our professional guides. With the help of a torch and a great desire to explore with us, you will discover the world of the oil mills with all their components : the different rooms of the hypogeal, the grinders, the presses, the storage rooms for olives and the places where the workers cooked and slept around the fire. Only Ostuni has an heritage of over 100 hypogeal oil mills but there are many others within the territory of Fasano, Monopoli and Salento .
