Touched echo, 2007
Markus Wilson

On February 13, 1945, during the final stages of WWII, large air raids by Allied Forces virtually flattened the old town of Dresden. Touched echo takes people right back to that fateful day.
Identifiable only by four small plaques, it is a place of silent contemplation rather than a monumental memorial. By leaning onto the railing of the terrace with the elbows placed on the railing and the hands covering the ears, visitors are able to hear sounds of airplanes and bombs exploding, transported from the railing via bone conduction, a technology developed for hearing devices.
it is completely silent unless you touch the railing.
