Platz des unsichtbaren Mahnmals - The Square of the Invisible Memorial
Above you can see the Saarbrücker Schloss (Palace). It has been the site of some castle or palace since mediaeval times. Its present contours were given to it by the famous baroque architect Friedrich Joachim Stengel in the 18th century, although it has suffered several bombings, fires and rebuildings since then. What you cannot see above is the aptly named invisible memorial. In 1993, the art professor Jochen Gerz and his students chiselled the names of 2,146 Jewish cemeteries on cobblestones and placed the stones in the square with the name-side down.
If you are thinking of visiting the palace, I would suggest you do it on a Sunday morning. Then a friendly ghost will give you a guided tour.
