The president is sworn in on the steps of what building?

Until 1977, the President was sworn in on the east steps of the US Capitol building. However, in 1981 Ronald Reagan requested that the Oath of Office be administered on the west steps. The reason was that Reagan wanted to face west to deliver his inaugural address thereby symbolically addressing the entire nation. Since then the Oath of Office has been administered on the west steps of the Capitol. (Taking the oath is required by the US Constitution before the President can take his office. )
