Washington city and district , is the capital of the United States of America

located at the confluence of the Potomac and Anacostia Rivers and flanked  by Maryland on the north, east and south-east and by Virginia on the southwest. The city of Washington is coextensive with the District of Columbia , the federal  district of the United  States . Washington was named  after George Washington and Christopher Columbus .The city’swas selected  by President George Washington in 1791.AFrench engineer and architect was commissioned  to plan the future capital. In 1800 the still unfinished city replaced Philadelphia as the nation’s capital.

Washington  is one of the few national capitals  founded solely as a seat of government. The  original plan of the city took into account its future growth. As the new republic increased  in size and wealth, Washington grew to become one of the most important and beautiful cities in the world. It is the site of impressive government buildings, magnificent monuments, important historical landmarks, fine museums, and broad, tree-shaded avenues and malls. Every year Washington is visited by millions of tourists from all parts of the United States  and from many other countries of the world. But the city is also home to a large number of people – the place where they live , work, and raise families. As such, it is confronted by the same problems facing most large cities . The city as a whole is divided into four quadrants ( northwestern, northeastern, southwestern and southeastern) by lines running north-south and east-west though the Capitol of the United States . The  central open space called the Mall is surrounded y public buildings and museums and I flanked on the east by the Capitol and on the west by the Lincoln Memorial. The broad Pennsylvania Avenue, which links the White House and the the capitol, is Washington’s ceremonial street and is the site of the president’s inaugural day parade. Capitol Hill is largely neighborthood of restored Victorian houses. Because  of its great size, central location , and elevated position on Capitol Hill, the Capitol dominates the Washington skyline. There is a law in Washington not to build structures higher than the Capitol , so it is the highest. The US Congress meets in this building. Visitors may attend congressional sessions to watch legislators in action.
