Berlin Morning Glow
When the sun shines on the Fernsehturm's tiled stainless steel dome, the reflection usually appears in the form of a crucifix. This effect was neither predicted nor desired by the planners. Berliners immediately named the luminous cross Rache des Papstes, or "Pope's Revenge". For the same reasons, the structure was also called "St. Walter" (from Walter Ulbricht).
