Independence Hall, where the Declaration of Independence was debated and adopted, is in Philadelphia.
The building was originally called the Pennsylvania State House. It stood in Philadelphia, which served as a major political center during the American Revolution and the early years of the United States.
The Second Continental Congress used the building when it considered independence in 1776. In 1787, delegates also met there during the Constitutional Convention, making the site important to both the Declaration of Independence and the Constitution.
Philadelphia was the national capital under the Continental Congress and later served as the temporary capital of the United States from 1790 to 1800. Washington, D.C., became the permanent national capital afterward, so it was not the city where the Declaration was adopted.
