From June 13 to 21, 2026, the picturesque Süßgrund in Lahnstein will once again transform into an open art landscape. But 2026 is special: The festival is inspired by the Golden Twenties — that turbulent era of artists characterized by Dadaism, Surrealism, and New Objectivity.
Today, these artistic impulses meet 80 contemporary artists from around the world: from the region, across Germany, Europe (France, Rivoli59 Paris as a cooperation partner), as well as from Japan, Brazil, Argentina, and Madagascar.
