The old bread oven of Torre de Arcas was communal property. This was a widespread model whose origins date back to the medieval period, when the construction and management of the oven was a lord's right — meaning this commercial activity could not be carried out privately. The current building may date from the 18th or 19th century, although there was likely an earlier oven on the site. Baking was handled by a baker appointed by the town council, but the preparation of the dough was each family's responsibility — usually the women's. They kneaded the dough at home and then cut and shaped the loaves at the oven. A family of 5 or 6 members typically consumed 30 loaves every two weeks. Users also had to supply their own firewood. The building has a rectangular floor plan with two diaphragm arches and still retains its original cobbled floor. The oven has a lowered barrel vault protected on the outside by a layer of earth. The current cast-iron doors are a later addition. Each baking session, which usually lasted an hour, produced around 150 loaves. In the early 1980s it was still in occasional use, mainly when large quantities of pastries were needed for a festival. In the late 1990s the building was restored for cultural and tourist purposes and turned into a museum. Currently not open to visitors.
