　　During the 50th anniversary celebrations for the Golden Gate Bridge， so many people walked across it that the middle of the bridge sank over two metres. The bridge designed by Irving Morrow， which was opened in 1937， is actually red， but is called " golden" because gold was discovered in California.

●Big Ben

　　Big Ben， which is officially known as Elizabeth Tower， is the nickname for the Great Bell in the famous clock.　The Great Bell， which began functioning in 1859， rings every hour. There are people whose job is to place coins on the pendulum to correct the weight and keep the clock on lime.
