Located on the Hudson Waterfront, the city was an integral part of the Port of New York and New Jersey and home to major industries for most of the 20th century. It is also well known for being the birthplace and hometown of American singer Frank Sinatra, one of the most popular and most influential musical artists of the 20th century, and there are parks and streets located in the city that are named for him. The character of the city has changed from a blue collar town to one of upscale shops and condominiums.[24]
