Almadén Mine, Historic mercury mine in Almadén, Spain.
The underground mining complex extends through multiple levels containing tunnels, shafts, and chambers carved into the rock formations of Sierra Morena.
The mine operated continuously for over 2000 years, producing approximately 250,000 metric tons of mercury until its closure in 2002.
The mining site preserves structures from different periods, including Roman galleries, medieval Arab extraction systems, and industrial revolution machinery.
The mining complex offers guided tours through restored tunnels, allowing visitors to explore mining techniques from various historical periods.
This location represents the world's largest mercury deposit, recognized by UNESCO as part of the Heritage of Mercury alongside Idrija in Slovenia.
