Luxembourg's development is rapid. In architectural terms, too, the country has ventured from tradition to modernity: Dunkl's first stop is the European Court of Justice, where the architect Dominique Perrault explains to him how, despite a long construction period, a great love story has been created.

In a suburb of the capital, he visits a provocative residential building by the architect Sharam Agaajani. Finally, Dunkl travels to Esch-sur-Alzette, where a former steelworks is being transformed into a place of knowledge. Architect Jim Clemes guides him through the site and introduces his unusual train station.
