The city’s birth was set in deep pre-history. Below its busy streets lie honeycombs of ancient cellars, catacombs and caves.
The city’s coffers benefit from organised tours of those ancient sites, but on the night of 30th April, only the foolhardy venture into those dank depths, for this is Walpurgisnacht when, at midnight, the Devil himself calls witches from world-wide to revel with him.
When Marvin Greenbaum took a film crew into the caves one Walpurgisnacht it was to ‘mock these ancient beliefs.’
Mr Greenbaum and five other gentlemen are now guests at the city’s Hospital for the Mentally Distressed.
