For over five decades, architect Friedhelm Grundmann (1925 - 2015) designed churches and subway stations - a unique achievement in post-war modernism in Germany. In 1961, it was a transportation project that made him known in Hamburg: the Lübecker Strasse subway station with its elegant concrete dome. In northern Germany, he received prominent commissions in various office partnerships, ranging from striking new buildings like the Simeon Church in Hamburg-Hamm (1966) to the reorganization of the medieval cathedrals in Lübeck (1973) and Greifswald (1989). He regularly returned to Hamburg's transportation projects, most recently for the renovation of the post-war modern bus and subway station Wandsbek-Markt (2005). This richly illustrated book comprehensively honors Grundmann's work for the first time. The common thread is the comparison of the two seemingly contradictory building types: church and subway. While church communities focused more on quality craftsmanship, the elevated railway allowed him room for innovative technical solutions. In both cases, Grundmann was committed to the needs of people and a measured modernity. A project of the University of Hamburg and the online magazine moderneREGIONAL.
