Berlin Kreuzberg Möckernstrasse the pitting of the stone louse still clearly evident; this building has witnessed some hard work. But do not believe that the hole in the centre is from the stone louse, no, that was a stray bullet from 1944. And additional these fine, almost invisible holes in the wall, thousands of black marks, flecks and scratches. Millions of little pieces of information which have collected over the course of a century transforming the plain wall into a rock face akin to the Saxon Switzerland. The building has sadly since been demolished to make way for a super-highway bypass.
