Construction of this world-famous building in the Gregorian style began in 1732. It was the Pennsylvanian state house and still would be today if it were not for the fact that the American Declaration of Independence was adopted here on 4 July 1776. The celebrated hero of the new nation was George Washington, then victorious commander in chief in the War of Independence and later first President of the USA. In 1787, after months of negotiations, the Constitution of the United States which still forms the legal basis of life in the US today was also drawn up in the same room as the Declaration of Independence. No other room in the United States has ever witnessed greater historical events of such import. Independence Hall is built in Georgian style and is considered one of the most elegant public buildings dating from the American colonial period with its lateral wings and tower on the south side.
