20 Breathtaking Wonders Of The World You Have To See

Golden Gate Bridge, San Francisco, US

One of America’s most iconic structures, the Golden Gate Bridge is the world’s most photogenic bridge. Construction on the ambitious project began in 1933 and took four years to complete, with significant loss of life among the workforce.

Its 4,200-foot-long suspension span made it the longest bridge in the world until 1964. Its characteristic International Orange color was chosen to ensure visibility in the notoriously foggy Bay Area.
