Influence of New York City is seen throughout the world although is not the capital of the United States. Its nickname, `Big Apple`, was given to it by early immigrants because the city seemed so huge and full of promise. It is located at the mouth of the Hudson River and lies on the same territory as the European cities of Naples and Madrid.

The Dutch founded the city in 1614, calling it New Amsterdam. However, in 1664 it was captured by the British and renamed New York. The city grew in importance and was the US capital until 1790. During the 19th century it was transformed by immigration and from the early 20th century became a world centre for industry, commerce and communication. With the economic boom came the construction of its skyline of skyscrapers, two of which, the Twin Towers of the World Trade Centre, were destroyed in the attacks of September 11th 2001, when nearly 3,000 people died.

New York is the most densely populated and cosmopolitan city in the US with 8, 214, 246 inhabitants speaking 170 languages. 36 % of the city`s population is foreign born. Five of the largest ethnic groups are: Puerto Ricans, Italians, West Indians, Chinese and Irish.

One in the three New Yorkers uses public transport to get to work, whereas in the rest of the US 90% of people go by car. The New York City Subway, which is open 24/7, is used by 1,4 billion passengers a year. New York is also home to the famous Grand Central Station, three major airports, and 12,000 distinctive, yellow taxi cabs.

The New York Marathon held annually on the first Sunday of November, is the largest marathon of the world. It attracts 37,000 runners. However, many New Yorkers prefer a less energetic jog round Central Park. New Yorkers are also keen baseball fans. The two most popular teams are The New York Yankees and The New York Mets.

About 40 million tourists visit New York City each year. Major attractions include the Empire State Building, the Metropolitan Museum of Art, Times Square, Central Park and, of course, the luxury shops along the Fifth Avenue. If you are fond of theatres, you can find a lot of them on Broad Way.

Tourist are also attracted by the incredible variety of places to eat, from diners with their burgers, bagels and pizza, to many of the finest haute cuisine restaurants in the US, and forgetting the Grand Central Oyster Bar, and the streaming hotdogs sold on every street corner. It is often called `The city that never sleeps` because there is so much to do and see.
