The Beit Tahara — a small ceremonial funeral house on the city's old Jewish cemetery — is the only building in Poland designed by Erich Mendelsohn, one of the most important German modernist architects of the early twentieth century. Built in 1913, it predates his more famous later work and shows the influence of expressionism in its angular forms.
It survived the war by accident and stood empty for decades. Restored in the 2010s, it now functions as the Mendelsohn House cultural centre with rotating exhibitions and concerts; the small permanent display on Mendelsohn's career is worth a half-hour. A 15-minute walk west of the castle.
