The Sava pits
The Sava pits are our biggest ore deposit of iron ore in Slovenia. The Sava pits (Savske jame) represent a proof that mining tradition, which has survived for almost 800 years, was strongly rooted in this area. The Ortenburg mining order from 1381 describes the freedoms, rights and responsibilities of miners. The Sava pits consisted of numerous mines, up to 90 m deep, which were used to dig siderite, and to supply two huge furnaces on Sava and Javornik.
