This is a gem of a place that can be easily missed. A green peaceful area on the banks of the river Barbadun a bit off the beaten path (25 Kms. from Bilbao), but well worth visiting.
I love visiting the Ironworks, the mill and the tower-house because it is always great to learn from where we came to understand where we are going. The ironworks dates back to the 16th century, more than 500 years of history. It operated until the mid-20th century and now, it is a museum.
Its old mechanical system still works today using water power. The site offers visitors a unique insight into the working aspects of the traditional iron industry in the 19th century. The ironworks, the forging capacities and the hydraulic infrastructure are very interesting. It is amazing seeing and hearing how they work waterwheels, the forge hammer, the fire, gears, millstones, etc.
Here are some pics from my last visit.
Definitely worth a visit!
