It is an unusual building built in 1755 and which has been a miners' hospital from 1774 to 1975. Later, after a few years of abandonment, it was rehabilitated at the beginning of the 21st century to show its dependencies. In addition, a museum space was created with three rooms: the first dedicated to the history of this building, the second, which is responsible for showing the process of mercury metallurgy and its evolution, and the third reflects the life and customs of the local and regional population. It was declared B.I.C. in 1992.
