The La Muela Museum specialises in disseminating techniques and traditions relating to the cultivation of olive trees and the production of olive oil. Through the different exhibition areas, visitors are given the opportunity of coming into more direct contact with the history of the olive, of understanding and learning about the economic and social significance of olive oil in Aragon, and in particular in La Muela. The museum is built in line with traditional architecture and extends over 1,760 sq. m. The collection is exhibited in four large rooms: the reception area, the ground floor, the loft and the basement. Exhibits include machines, tools, samples of products and information panels about the world of the olive and olive oil. In the central square stands a remarkable 1300-year-old olive tree, while a Roman stone olive mill welcomes the visitors. The first room or "Machine Hall " is the main attraction of the museum. The exhibits present the four stages of olive oil production: harvesting, crushing, pressing and separating. On the wall of the ramp leading to the basement, a 150 sq. m. mural illustrates the mythological origin of the olive and the traditional methods and techniques used to export and market in the Mediterranean basin. Room 9 or the "History Hall" uses a well for the exhibition of mechanical models. A small Arabic mill operates in the upper part of the well. Next to this are a press dating from 1826, a reconstruction of a Roman olive mill, a statue of Hercules and a 100-year-old olive tree.
