ORBAIZETA ROYAL AMMUNITION FACTORY
Historic ruins from the 18th century in a natural setting, with a restored kiln building.
An imposing 18th-century military factory sits in the Txangoa ravine, a strategic location chosen for its abundance of timber and iron. Its proximity to the border resulted in a turbulent history marked by looting. Declared a Site of Cultural Interest in 2008, the site features accessible ruins and a restored furnace building.
