WASHINGTON, D.C

Washington, the capital of the United States is situated on the Potomac River in the District of Columbia. The district is a piece of land which does not belong to any one state but to all the States. The district is named in honour of Christopher Columbus, the discoverer of America. It is very interesting that Americans never say simply Washington. They always add «D.C.» as the indication of the location. It is important because there .are many towns with the same name all over the country and even one large state in far north-west. Washington was founded in 1791 as the capital of the United States of America. Washington is quite a new city. The population of the city is nearly one million people. It is not a very large city, but it is very important as the capital of the USA. There is a law in Washington against building structures higher than the Capitol. Washington has many historical places. The largest and tallest is the Capitol,

where the Congress meets. It is a very beautiful building with white marble columns. Not far from the Capitol is the Library of Congress. It holds five million books. The White House, the residence of the president is the oldest public structure in the capital and one of the most beautiful. It was built in 1799. It is a two storied whit e building . Not far from the Capitol is the Washington Monument, which looks like a very big pencil. It rises 160 metres and it is empty inside. A special lift brings visitors to the top in 70 seconds, from where they can enjoy the view of the city. The Jefferson Memorial was built in memory of the third President of the USA Thomas Jefferson, who was also the author of the Declaration of Independence. The Memorial is surrounded by cherry trees. The Lincoln Memorial is devoted to the memory of the sixteenth President of the USA, the author of the Emancipation Proclamation, which gave freedom to Negro slaves in America.
