Memorial of the Gray Buses, Holocaust memorial in Ravensburg, Germany

The Memorial of the Gray Buses is a concrete sculpture shaped like a bus, its front facing left with a rounded wheel arch, a low horizontal grille and a recessed windshield split by a central pillar. Five shallow rectangular window recesses run along the side beneath a rounded roof, and the whole form rests on a low continuous base. The memorial is inscribed with the question "Wohin bringt Ihr uns?" (Where are you taking us?).

From 1939 to 1945 under Nazi rule, more than 70,000 people were transported from medical facilities to locations where they were killed in what became known as Aktion T-4. This systematic program targeted those the authorities deemed unsuitable to live.

The memorial takes its name from the grey buses of the Gekrat transport company, which collected patients from Weißenau; 691 were deported to Grafeneck in 1940 and 1941. The inscription "Wohin bringt Ihr uns?" ("Where are you taking us?") reproduces a patient's recorded question. Artists have responded to the memorial with short films and a performance text by Michael Helming.

The permanent installation at the former sanatorium is accessible and can be visited without special preparation. The traveling bus visits different locations, so checking ahead about its current position helps ensure you can view it during your visit.

The installation deliberately blocks the entrance gate of the former medical facility, symbolically interrupting normal access to the grounds. This placement directly links the physical presence of the deportations to the place where people once carried out their daily work.
