The White House: It was built in 1792 and was completed in 1800. The site was selected by the founding father of the United States, the first President George Washington. Starting from the second President John Adams, all successive U.S. presidents used the White House as their official residence. Over the years, the White House became synonymous with the US government. In 200 years, the White House complex has a strong British architectural style, and later has integrated the American architectural style. “Simple and elegant” is the main architectural style of the White House.
