Appearance introduction: Viewed from a distance, the Capitol Building is a building surrounded by huge columns, with a crown-shaped dome building in the middle, about 94 meters high, about 246 meters long from north to south, and wide from east to west. 115 meters, with 540 rooms. The exterior walls of the Capitol Building are all made of white marble, which is pure white and gives people a sacred and pure feeling. The entire Capitol building is a three-story flat-roofed building with a tall dome in the center, also divided into three floors. There is also a small round tower on the dome, and on the top of the tower stands a 19-foot-tall (about 5.8 meters) bronze statue of the Statue of Liberty. With a feather crown on her head, a sword in her right hand and a shield in her left hand, she always looks to the east where the sun rises. She is the most eye-catching road sign in Washington.
