Built in the mid-19th century, the press was relocated from a wealthy homestead of the Koszyk family. The press was used to extract oil from linseed and saw its most extensive use during Lent and Advent when fat was added to food. The press was a service outlet where owners of the raw material worked under the supervision of the press operator. For oil extraction, the customers would bring linseed (the most common raw material) or, more rarely, hemp or poppy seeds or plum kernels. There are two rooms inside: the hallway and the workshop. Some preliminary production activities took place in the hallway; this was where dried flax seeds were beaten and, after that, passed through thick strainers several times. The workshop is mainly a production room. There are two large troughs hollowed out in spruce timber there and numerous hollow basins in which the flour obtained by beating was kneaded with hot water. There is an oven to the right of the entrance. A copper bowl in which the prepared mass was heated is built into the hearth. Extraction was the last stage of the oil production process and was done with a screw and wedge press. The oil mill was in operation until 1950.
