The spring


Due to the impermeable Taunus quartzite, the water from the spring came to the surface relatively high up in the hills.
As recently as the 19th century it could still boast running water the whole year through. It flows into reservoirs. Under the wall, an outlet channels the surplus water to the outside.


The spring has a protective significance. In times of siege, there was plenty of water for men and the animals alike.



Apart from water supplies, it was also necessary to store food within the fortress. This would have consisted of various grains that were cultivated and harvested in the surrounding area. Typical varieties were husk barley, two-grained wheat, one-grained wheat, spelt, oats and common wheat. Furthermore, pulses such as lentils, peas and common vetch were cultivated. Added to this is livestock breeding. Swine (approximately 53%) and cattle (approximately 34%) were bred. Dogs as well as water fowl featured on the extended menu. By contrast, hunting played only a subordinate role.
