In which building did delegates primarily sign the United States Declaration of Independence?

Delegates primarily signed the United States Declaration of Independence in Independence Hall.

The building was called the Pennsylvania State House in 1776 and stood in Philadelphia. It was later renamed Independence Hall, the name by which it is now internationally recognized. The Second Continental Congress met there while debating and adopting the Declaration.

The famous parchment was signed primarily on August 2, 1776, rather than in a single ceremonial signing on July 4. The building also hosted the Constitutional Convention in 1787, linking the Declaration with the later creation of the United States Constitution. Carpenters’ Hall, another Philadelphia meeting place, hosted the First Continental Congress in 1774, which is why it can be confused with Independence Hall.
