This long, thin island is only one of New York City's five boroughs, but it's Manhattan that has the concrete canyons and the inimitable skyline; Manhattan that has the world's brightest and most renowned theater district; Manhattan that has Central Park, Rockefeller Center, the Guggenheim Museum, and the World Trade Center site; and Manhattan that comprises iconic neighborhoods like Harlem, the Upper East Side, Times Square, and Greenwich Village.
The rest of New York City has much to see and do, but it's Manhattan that represents the city—and sometimes the entire United States—to the world. You could spend a week on this tiny island and still not see all there is to see. Grab a yellow taxi, hop on the subway, or just start walking, and you're sure to begin to understand just what it is that makes Manhattan, Manhattan.
Wall Street is a 0.7-mile-long (1.1 km) street running eight blocks, roughly northwest to southeast, from Broadway to South Street on the East River in the Financial District of lower Manhattan, New York City.
Over time, the term has become a metonym for the financial markets of the United States as a whole, the American financial sector (even if financial firms are not physically located there), or signifying New York-based financial interests.
