Due to the fact that Massari was surrounded by filed of olive orchards, the village had at least two Olive Mills.  One of them was situated next to the house of Charalambos Michael (Fattalla) and the other next to the house of Stavris (Tourkopoulos). The payment by the olive owners to the owner of the Olive Mill was made in kind not with money and was estimated on the quantity of olives that were processed.
