🏰💧 What made a castle truly strong: high walls or something hidden?
During the Middle Ages, castle sieges could last for months. Water was one of the most important needs. When access to rivers and wells outside the castle was cut off, people had to rely on the resources inside the fortress.
This is why the deep well of Nuremberg Castle was so important. Carved directly into solid rock, the well reaches about 50 meters deep and provides access to underground water.
Today, visitors can see its impressive depth when a light is lowered into the well. The disappearing circle of light shows the remarkable engineering skills of the Middle Ages.
Strong walls could keep enemies out, but a reliable water supply was often what kept a castle alive.
