Once a year, the city of Pulheim invites an artist to create a work in or at the synagogue that addresses the significance of the historical site, raises awareness of the past, and meets the highest artistic standards. Since then, renowned, partly world-famous artists have worked in the Stommeln synagogue – Jannis Kounellis and Richard Serra, followed by Georg Baselitz, Mischa Kuball, Eduardo Chillida, Maria Nordman, Carl Andre, Rebecca Horn, Giuseppe Penone, Roman Signer, Lawrence Weiner, Rosemarie Trockel, Richard Long, Sol LeWitt, Santiago Sierra, Maurizio Cattelan, and Olaf Metzel. In 2007, Max Neuhaus developed a permanent sound installation based on halachic (traditional Jewish) timekeeping, acoustically projecting the synagogue into the center of the place. Neuhaus’ sound installation is heard 13 times daily in the marketplace.
