In the course of the 1998 campaign, the excavation of a smithy made a new contribution to the existing data on the Mediaeval settlement.

The project: "Experimental Archaeology. Metallurgical production technologies associated with Mediaeval agriculture" (DGICYT, HUM2004-05280), also funded by the Ministry of Education and Science and carried out by the same team at L’Esquerda through the University of Barcelona, focuses entirely on metalworking, especially iron and bronze, always associated with agriculture, i.e. the production of tools and vessels for working in the fields.

In the ÀREA de L’Esquerda, a small forge has been reproduced for forging iron: a medium-sized stone fire, a bellows, and an anvil.

To cast bronze the old-fashioned way, a furnace was built near the forge, supported by a wall. The first experiments made it possible to melt at high temperatures and to pour the metal from the crucible into a stone mould.
