The Navy plans to spend $600,000 for “camouflage” landscaping and rooftop adjustments so that 1960s-era barracks at the Naval Base Coronado near San Diego will no longer look like a Nazi swastika from the air.

The resemblance went unnoticed by the public for decades until it was spotted in aerial views on Google Earth.

But Navy officials said they became aware of it shortly after the 1967 groundbreaking, and had decided not to do anything.

“There was no reason to redo the buildings because they were in use,” a spokeswoman for the base, Angelic Dolan, said. She added that the buildings were in a no-fly zone that is off limits to commercial airlines, so most people would not see them from the air.
