Brooklyn (its name as borough of the city of New York; it is also Kings County, a county of the state of New York), the "Borough of Homes and Churches," is one of the five Boroughs of New York. It used to be and still feels much like a city in its own right, with approximately 2.5 million inhabitants. If separated from the rest of New York City, Brooklyn would be the 4th-most populous American city. (Brooklyn Wikitravel)
