The water catchment of the Schlossberg fountain is unique in the region.
It was a water supply consisting of an arch-shaped dead well extending
around the toe wall. Originally it was 60 meters long, today only a short
part is left. A few year ago it was labouriously renovated. Systems like
that existed in the middle ages, but we don´t know the date of construction
of our dead well.
Under particular geological condicions some sediment layers may contain water.
To collect this water, small channels were cut into the rock. A large wall made
of sandstone was erected and large stone slabs were used to cover the system.
This tunnel prevented the water from dirt and evaporation.
