Washington, D.C. – capital of the USA

1. Washington is the seat of government of the USA. You know that the flag of the USA – the Stars and Stripes-has fifty stars on a blue background. Each of these stars represents one of the fifty states. But the City Washington is not in any of these states. It occupies the District of Columbia, abbreviated into D.C. and the name of the capital always goes with this abbreviation (don’t mix it up with another Washington, which is a state on the Pacific Coast). The population of Washington, D.C., is about 900.000 and together with the suburbs (the metropolitan area) its population is over 3.000.000.

2. Washington is like no other city of the USA. New York is a centre of finance, of shipping, of fun. But Washington’s only industry is government. The white House, where the US President lives and works, the Capital, the home of the Congress, and the Supreme Court are all in Washington, D.C.

3. Washington, D.C. is one of the few capitals in the world that was simply ordered to exist for housing the nation’s government. President George Washington, in whose honour the city was named, picked out the spot that included the old tobacco-trading Potomac River port of Georgetown, not far from Georg Washington’s own home of Mount Vernon. The Congress approved the choice. The city belongs neither to the North, nor to the South.

4. The Capital, seat of the US Congress, is the building which got the name from the temple in Rome. The word is also applied now in some states to the state houses. Building of the Capital in Washington, D.C., was begun in 1793. The white House is official residence of the presidents of the USA, located at 1600, Pennsylvania Avenue.

5. The library of Congress is “the biggest existing library”, which contains more than 13 million books in various languages, more than 19 manuscripts, including the personal papers of many presidents and many other items such as maps, prints, recordings, etc. The Library serves the Congress, the entire governmental establishment and the public at large. The law of 1870 makes it obligatory to send to the Library two copies of every American book, newspaper or any other published item.
