Big Tipi, Entertainment tent in Fredenbaumpark, Dortmund, Germany

The Big Tipi in Dortmund's Fredenbaumpark is a tent structure 35 metres high with a diameter of about 25 metres and over 360 square metres of covered space. It was designed by scenographer Michael Wienand as a temporary exhibition hall for Expo 2000 in Hanover, with technical planning by architect Ralf Schulte-Ladbeck. After the Expo it was bought by the city of Dortmund and now serves as a climbing and event centre for experiential youth work.

The tent was originally built as an attraction for Expo 2000 in Hannover before relocating to Dortmund's Fredenbaumpark. It has since become an established fixture that draws visitors from across the region.

The Big Tipi's name comes from its form as a giant Native American-style tipi. It was designed by scenographer Michael Wienand as a temporary exhibition hall for the EXPO 2000 children and youth platform, led by the German Federal Youth Council. During the expo it hosted the Kindergipfel 2000, and over 2.7 million visitors were guided by volunteers from member youth organizations.

The Big Tipi stands in Fredenbaumpark and is used for climbing and experiential youth work; the city bought it after Expo 2000. It was closed from autumn 2010 because of wood rot and stability problems, and reopened in 2014 after a renovation costing 670,000 euros.
