From the Middle Ages up until the recent past, mining left behind characteristic above- and below-ground installations, such as head frames, shaft buildings, mine forges, administration and assembly buildings, shafts, mine workings and adits. The dressing, smelting and processing of the mined raw materials generally took place in the immediate vicinity of the mines, as is demonstrated by smelteries, mining works, stamp mills and forges. How the installations functioned is documented by preserved technical facilities, such as bellows, waterwheels, turbines or steam machines, amongst others. A prerequisite for the operation of the mines and smelteries was the establishment of mining infrastructure that served not only as a means of transport but also supplied energy to the mines. Today the well-preserved systems for mining water management bear witness to this infrastructure.
