Vitra Design Museum

Because Basel lies right on the international border, some of its suburbs spread over into Germany and France. 

So it is with the Vitra Design Museum, which although considered a Basel institution, is a five-minute train ride just across the German border from central Basel. 

By any measure, it is one of the world's most important museums of design. The building itself is a landmark, designed by Canadian architect Frank O. Gehry. 

Inside are changing exhibitions - two or three each year - examining current and historical design trends and themes. The displays are stunning and provocative, often inviting interaction.
