Zwickauer Mulde

Stein Castle on the rocky river bank near Hartenstein

The valleys in the catchment area of the Mulde were presumably used from the end of the last cold stage as access routes into the Ore Mountains that was covered in dense, ancient forests. This is evinced by the remains of artifacts left behind by Old Stone Age hunters, as well as Bronze Age and Iron Age discoveries as far as the higher regions of the Ore Mountains.

The castle ruins of Isenburg

Later, the western Ore Mountains became the territory of Germanic and Slavic tribes. Paths, trade routes and military roads, linked the old settlement areas around Leipzig and Altenburg with Bohemia. The mule tracks, however, avoided the rivers in favour of the ridges. At unavoidable river crossings, (fords, later ferries and bridges) and at intersections castles, villages and monasteries were established. Of the palaces and manor houses, Rochsburg, Rochlitz, Wolkenburg, Waldenburg, Forderglauchau, Hinterglauchau and Osterstein have survived. Of the castles, Wiesenburg, Stein Castle and the Isenburg remain. Fortifications constructed in the side valleys include Hartenstein, Wildenfels and Schwarzenberg. With the discovery of the rich silver deposits in the late Middle Ages, settlements grew up around the source streams in the upper Ore Mountains and the mining towns emerged.
