Look for the statue of George Washington in front of the main facade of the capitol.
Washington was the first president of the United States (from 1789 till 1797) and commander in chief of the revolutionary Continental Army in the United States War of Independence against England.
In the War of Independence both France and Spain contributed greatly to the victory of the Thirteen colonies against England. To prove it there are two cannons which are guarding the statue of George Washington. Where are those cannons from?
