Celle Castle, Germany

The Cell Palace is one of the most beautiful palaces of the Welfs and one of the oldest  princely houses existing still today. Over the centuries, the originally simple castle has undergone reconstructions and was constantly extended to become an elaborate and magnificent four-wing construction. The palace accommodates a palace theatre. HI-FOG®protects the stage areas and the theatre’s attic with three gas-driven pump units (GPU) independent of power supply.
