Since it opened on this day in 1937, the Golden Gate Bridge has become perhaps the defining symbol of San Francisco. It’s a city famous for reinvention, one that rebuilt itself after the devastating earthquake and fires of 1906, later becoming ground zero for hippie culture in the 1960s, before morphing again into the urban hub of Silicon Valley. San Francisco is often called one of the most beautiful cities in the United States, and with views like this, it’s easy to see why.
