This is a preserved 19th century industrial complex situated on an ancient gypsum quarry. The furnaces on site were used to dehydrate the gypsum to produce the plaster used in building construction and religious statues.

At the start of the 21st century, the government of Valencia decided to carry out a restoration project to make this a tourist and educational site. They spent over 280,000 Euros on restoring the furnaces, buildings and making a small visitors centre. Then, they learned that the site was actually privately owned.

So, they spent the money, but can’t take credit for it, administer the site, or make any money from it. The actual owners, though, are very nice though, they let people wander the site to learn about the history.
