In which building was the U.S. Constitution signed, a site connected with America250 history?

The U.S. Constitution was signed in Independence Hall, a site connected with America250 history.

Delegates signed the Constitution in Philadelphia on September 17, 1787. The building was then known as the Pennsylvania State House. It had already hosted the Second Continental Congress and the debates that led to the Declaration of Independence, making it central to both the 1776 founding story and the later creation of the federal government.

The building acquired the name Independence Hall during the nineteenth century. It is now part of Independence National Historical Park and is recognized as a major American historic site.

A common mix-up is Federal Hall in New York City, where George Washington was inaugurated as the first U.S. president in 1789. Carpenters’ Hall in Philadelphia hosted the First Continental Congress in 1774, but it was not where the Constitution was signed. Independence Hall is the canonical answer for the 1787 signing location.
