The laser installation by Margareta Hesse (* 1956/D) in the historic cellar in Berlin burn and glow red trails in the darkness under the earth. (see catalog “Laser.Licht.Raeume” by Pamela C. Scorzin, 2011) The large, labyrinthine cellar from the 15th century under the residence of mayors and Prussian regimental commanders in Spandau can be carefully wandered by the visitors and they meet the glaring red light. At first you may be afraid of being hurt by the light.

Addional comes a very disturbing, almost aggressive humming and hissing, unknown, threatening sounds and sounds swinging through the cellar. The enormous effect of the laser installations lies in their intensity: one can not escape the emotional high voltage which the laser light generates in the cellar.
