The Tusculum is a former garden pavilion of the Villa Lindner at the "Landgräfin Anna-Elisabeth-Weg". The Tusculum fascinated Otto Dix (1891-1969), one of the most famous painters of German Expressionism, during his time in Düsseldorf as a member of the painters' group "Das Junge Rheinland" when he stayed in Sankt Goar in the 1920s. Dix was married to the youngest daughter of the Lindner family and thus frequently spent time in Sankt Goar in the 1920s. This is also where a significant portion of Otto Dix's seminal work "The War" was created. The pictures painted here showed and made clear to people the war in all its horror.
