The Kunstverein Ludwigsburg, a long-running independent contemporary art association founded in 1979, runs an exhibition space and project programme in the old town. Shows rotate every few months and tend to focus on emerging German and international artists working in painting, sculpture, and installation.
The space is small but consistently interesting and a useful counterweight to the baroque heritage that dominates everything else in Ludwigsburg. Opening hours are limited (typically Wednesday to Sunday afternoons); admission is free or low cost. Check the current programme before visiting — between exhibitions the space is closed for installation.
