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.
