The Oil Museum of Palazzo Montesano is housed in the basement of the Palazzo Montesano, in seven rooms, with barrel vaults; in these rooms there are instruments of olive oil extraction technology. A press dating back to 1614, a stone grindstone, jars, oil measuring instruments and one hundred and one hundred various tools and furnishings. Objects of common use and ingenious devices, specific to images and rural environments.
The "relics": an iron cafiso (typical oil container), a hydromechanical press of the early twentieth century. In the rooms it is possible to admire, among other things: large and narrow-mouthed tin jars; quarter with two side handles with narrow neck and lid, oil tanks, iron hoe, iron plough with pointed ploughshare and wooden plough with broad-pointed iron ploughshare; vintage corbelle, baskets, iron pruning scissors, hacksaws (sirraculi) and hand drill (virrina).
