The Mystery Park near Interlaken in the Bernese Oberland is to reopen its doors for a final season this summer - after going bankrupt in 2006.
The theme park, the brainchild of Swiss author Erich von Däniken who believes that extraterrestrials contributed to human civilisation, features a number of "unsolved puzzles" such as the origins of Stonehenge and the pyramids.
Marcel Meier, the manager appointed by the new owners, told Tuesday's Berner Zeitung newspaper that they believe the current economic crisis offers them a chance to make it a goal for family outings. They think that people will cut down on travel and look for attractions nearer home.
The park will keep to the basic mystery theme, but it will be more family-friendly. There will be a large playground for children and the entrance price will be lower than it was under the original management.
Von Däniken himself will take part in the enterprise, giving a series of lectures.
Meier said that although the park had not been used since 2006, it was in good condition. However, SFr100,000 ($87,904) is to be invested to bring it up to standard.
The ultimate fate of the Mystery Park after it closes its doors at the beginning of November remains – a mystery.
