April Fool's Day or All Fool's Day occurs annually on April 1. The day is generally observed by playing a practical joke on a "victim" who soon becomes known as an April Fool. This custom is thought to have started in France during the 16th century but the British are credited with bringing it to the United States.
The United States Capitol is among the most architecturally impressive and symbolically important buildings in the world. It has housed the meeting chambers of the Senate and the House of Representatives for almost two centuries. Begun in 1793, the Capitol has been built, burnt, rebuilt, extended, and restored; today, it stands as a monument not only to its builders but also to the American people and their government.
