The large ruins of the castle stretch out on top of the Eisenberg. The well with its 25 meters deep is particularly impressive, as mining within the castle used to be carried out here. From the Georg Victor Tower you have a wonderful view of the complex. The ascent is free and open during the day during the summer months.
