With this name we refer to the north corner of the village where two complex structures were found and identified as metallurgical furnaces, a forge or a metal workshop. A third furnace was discovered below the two first which gives us the idea that the area was consecutively used for the same purpose during a long period of time. The furnaces have an oval shape with a stony plinth and earthen dome made and destroyed during the melting process, a small hole in the plinth gave the access to the furnace. Within the area pieces of metalworking as nails, knives or tools and more than 50k of iron slag were found. Metallography analysis carried out by the Complutense University team of Mechanic Technologies and Archaeometallurgy (led by the professor Antonio J.Criado Portal and the technicians Laura Garcia Sanchez and Antonio Javier Criado Martín) we know that the furnaces obtained iron from melting the gangue by reduction. The extracting areas of the metal raw materials are close to the settmente because the analysis of metals from the nearby area revealed similitude with pieces of raw iron in the Sierra de la Culebra mountain range no more than 15 km North the site.
