Since it was opened , it has been perhaps the best-loved sight of San Francisco. But whoever goes to see the bridge can see the bridge is red instead of golden . Do you want to know the reason why is called  the Golden Gate Bridge?

In fact the bridge isn’t named for its color .It is named for the Golden Gate. What is the Golden Gate? A gate is either an opening or the thing that closes the opening . the Golden Gate is an opening in the land . Water from the sea comes through this opening into San Francisco Bay 旧金山海湾And the bridge goes over the opening . And do you know why it is called the Golden Gate? Here is a story about it .

Many years ago ,men from some European countries came to California to look for gold . Many of them came by ship . When they came into the bay through the opening , they thought it was a gate to gold , so they named it the Golden Gate.
