Dam of the Cannon Factory

The Royal Cannon Factory has left few remains. The wide dam in Miera river is one of them. It had an important role during early 17th century for valley wood use.

The installation of this iron factory meant the use of wood as fuel for the smelting  process, and water as an energy generator. The dam is an engineering work that allows the flow of the river to be directed to the channels that gave service to the factory.

After two centuries of work, it had smelted 300,000 Tm of iron after having consumed 250,000 Tm of vegetable carbon from the deforestation of 140,000 ha.
