In October 2010 the extended Kaltbach caverns in Switzerland were ceremonially opened together with the visitor centre following a two year construction period. WWP successfully introduced the idea to hold the complete event in the passages of the Kaltbach cavern. The challenging implementation included an elaborately staged blasting operation, logistically sophisticated cavern viewing and a cooking demonstration by celebrity cook Anton Mosimann.
