‘We have to build a park for the family, not just serve one target group. The family is our target group,’ is Franz Mack's credo. For its 40th anniversary, the Mack family looks back together on the history of Europa-Park. Roland Mack talks about the beginning of a great idea. Jürgen Mack explains what a balancing act it was to combine the production of rides at Mack Rides in Waldkirch and the management of the theme park in Rust. Illustrated descriptions show how Europa-Park became a cornerstone and meeting point of Europe. Michael Mack indulges in childhood memories and Thomas Mack remembers his first job at Europa-Park. The values that characterise the family business become clear: solidarity, gratitude and tireless work on a vision. Everyone shares a common motivation: to see laughter in the eyes of children.
