Pictures: december 28th, 1995
Pallaruelo in his Los Molinos del Altoaragón devotes several pages to this site. There is also a picture showing the sorry state of the building at the beginning of the 1990ies.
The construction of the caracol is most interesting. The screw is mounted on a circular stone resting in a round pit. Add some oil for a smoothly running caracol. The base of the caracol shows two perforations for the poles used to rotate the caracol and thus heighten the pressure.
The center image below shows one of the concrete containers (named algorín) used to stock the fresh olives waiting to be processed. An azulejo connects each container with a person.
