The Zollverein Coal Mine Industrial Complex, a testament to the industrial history of Germany, was once among Europe's largest coal mines. Founded in 1847, it functioned until 1986, becoming a symbol of the region's economic development through its peak years. Today, it stands as a UNESCO World Heritage Site, recognized for its unique contribution to industrial architecture and its role in the heavy industry of Europe. The complex now serves as a cultural and educational center, housing museums and art exhibitions that celebrate its rich heritage.
