Legends are stories about the past. Some of the stories come from ancient history. But not all legends are ancient. There are modern legends too. They are often called urban legends, because the stories happen in modern cities. Ten years ago, there was a rumor that there were crocodiles under New York. The rumor was soon a newspaper story, and the newspaper story was soon a legend. So, today, many people in New York believe that there are crocodiles under the ground there!
