Porta Del Parco Nazionale Colline Metallifere is a metal extraction and processing site which was established in 2003. There are two mining areas preserved for the public viewing namely Rock Park or Parco Delle Rocce and Ravi Marchi. The Tunnel Museum set up within the 150-metre tunnel acts as an educational centre to enlighten the visitors about the usage of store explosives, the developmental stage of the mining operation and the support work. Through the representation of images, lights, and sounds, the museum seeks to make the experience vivid. The tunnel will lead you to the San Rocco Church, Rock Theatre, and the Teatro dele Rocce. The restored surface facilities of the archaeological site of Ravi Marchi are also notable features of Porta Del Parco Nazionale Colline Metallifere.
