Where was the United States Constitution signed in 1787, a landmark in America250 history?

The United States Constitution was signed at Independence Hall in Philadelphia in 1787.

The building was then called the Pennsylvania State House. It had already hosted the Continental Congress during the Revolutionary era and was the meeting place where delegates debated and signed the Constitution. The signing occurred on September 17, 1787, at the end of the Constitutional Convention.

Thirty-nine delegates signed the document, representing twelve states. Rhode Island did not send delegates to the convention. George Washington presided over the convention, and Benjamin Franklin was among the delegates who supported the finished Constitution. The document then went to the states for ratification.

Independence Hall is closely associated with both the Declaration of Independence and the Constitution, which makes it especially important to America250. It is part of Independence National Historical Park in Philadelphia and is recognized as a major site in the founding history of the United States. Federal Hall in New York City, by contrast, is associated with the first presidential inauguration and the early federal government.
