In the rock under Castle Hill

Rock vault under Castle Hill today.

Since the fourteenth century, according to the records, the rock beneath Nuremberg Castle has been riddled with vaults and passageways with a total area of about 25,000 square meters.

These are not natural caves; they were laboriously hammered and chiseled by hand out of the native rock. Because of their consistent cool temperature, these cellars – going as far as four stories down – were ideal for making and storing beer.

Walkable passageways in the stone also served as a water supply system.

The extensive system of vaults and galleries under the Castle and the northern part of the Old Town was ventilated by an ingeniously simple trick: Strategically placed air shafts acted as a passive fresh air circulation system that worked superbly for centuries.
