THE MYSTERY OF THE HELVETIA
Dive into a historical investigation in the heart of Nyon and travel back to 1858, at the time of the mysterious sinking of the Helvétie. Guided by photographs taken by Louis Kunz, a Nyon-based photographer from the late 19th century, wander through the town’s streets between the old town and the shores of Lake Geneva, explore archives from another era and piece together the clues to identify the swindler who stole the victims’ compensation.
