Designed by Lahdelma & Mahlamäki Architects, the Lost Shtetl Museum tells the story of Jewish life in Šeduva before the Holocaust. In the summer of 1941, 664 of the town’s Jewish residents were murdered, a fate repeated across more than 200 Lithuanian shtetls. Julian de Metz examines the building’s relationship to its highly charged physical and cultural context, and asks to what extent architecture can – or should – seek to shape collective memory and conscience.
