A U.S. Navy barracks in Southern California that resembles a swastika from the air is to get a 600,000 U.S. dollar make-over after spawning myriad conspiracy theories and concerns among Jewish groups. On the ground, the four L-shaped buildings are simply part of the U.S. amphibious base at Coronado island in San Diego. But the growing popularity of satellite images from Google Earth alerted people to the fact that they are shaped like a swastika when seen from above. The Anti-Defamation League (ADL) campaigned for modifications to the building. After nine months of talks, the ADL said the the Navy told them this week it would spend 600,000 U.S. dollars on landscaping and architectural changes that would obscure the swastika shape from the air. The Navy has said the buildings, which serves barracks for the Seabees, were constructed in the late 1960s and were not intended to resemble the Nazi symbol. But that has done nothing to silence theories circling the Internet in the past two years. One suggests they were built by German prisoners of war who slipped the layout past the Navy. Another hypothesis suggests the shape was intended to help the buildings survive bombing formations used by the Japanese navy.
