This ensemble of buildings has been restored and refurbished in its entirety to provide an understanding of the iron industry.

The forge building is organized around two rooms that housed the hydraulic devices: the forge hammer and large bellows, as well as the furnace, which is included in the same area housing the hammer.

The site is complemented by the hydraulic system consisting of the dam on the river, channel and man-made pond or "banzao" for accumulating water.

The main features of this forge are: the diversion of the river using stones, the channel dug in the ground, the "pond" formed by stone slabs sunk into the ground, except in its final section, which is wooden, and the nozzle through which air is blown into the hearth, which is also made of wood.

As regards the smithy itself, it is one of the most interesting examples of its kind due to not having undergone major changes over time.

The building is constructed in irregular stone masonry in its walls and roofed with slate shingles fixed with nails to battens resting on wooden sleepers and beams. Three elements are found outside the building:

  • The dam, constructed of overlapping stone slabs.
  • The channel about 350 metres in length, dug in the ground itself.
  • The "pond", formed by slabs of slate stone sunk lengthwise into the ground, with its final section being made of wood.


    As for the forge hammer, the most noteworthy mechanisms are the waterwheel, made of oak, with an external diameter of 2.3 metres, and the axis or arm, also made of oak, with a length of 5.13 metres and equipped with protective iron elements, etc..

    The nozzle through which air is blown into the hearth is one of the most curious elements of the site. It is made of wood, as are the pipes joining it to the hearth.

    There are two hearths: the main one, situated next to the hammer and supplied with air from the nozzle, and another, secondary hearth serving as the forge, with hand-powered bellows.
