Where was the Declaration of Independence adopted?

The Declaration of Independence was adopted at the Pennsylvania State House.

The building stood in Philadelphia and is now called Independence Hall. The Second Continental Congress met there when it approved the Declaration on July 4, 1776. The site later hosted the Constitutional Convention of 1787, giving it a central place in both founding-era milestones.

The Pennsylvania State House was completed in 1753 as the colonial government’s principal building. Its Assembly Room became the setting for debates over independence and, later, the Constitution. The structure is part of Independence National Historical Park.

Visitors sometimes use “Independence Hall” as though that was the building’s original name. That name became established later, reflecting the historic events associated with the site. It was also called the Old State House in some early references.
