have a 1986 map of Potsdam in which the areas where there were Stasi buildings—anything from bunkers to multi-storey edifices to shooting ranges—are left blank. On another, a 1984 map of East Berlin, entire city blocks and streets in Stasi areas are simply not represented: they are pale orange gaps in the map. Out of curiosity I look up Golm, and find that it is a gap on the map, on the outskirts of Potsdam.
