When the last miners left Gonzen iron mine in 1966, the compressors fell silent and the rattling of the boring hammers was no longer to be heard.

Since 1983, visitors have had the opportunity to dive into this exciting underground world. The tour takes you along tunnels and galleries, past deep silos and sinks. The changing colours and the impressive iron ore layer amaze throughout.
