The National Constitution Center cost $15 million to renovate in 2025
The National Constitution Center in Philadelphia is a non-profit organization that serves as a platform for constitutional education and debate. The center was created by the Constitution Heritage Act of 1988, which was signed by President Ronald Reagan. The act directed the establishment of the center within or close to the Independence National Historical Park. The National Constitution Center broke ground on September 17, 2000, 213 years after the Constitution was signed, and it opened on July 4, 2003. The center has since become a cultural hub in the city, attracting a million visitors annually.
The center's address at 525 Arch Street was specifically chosen because May 25 (5/25) is the date the Constitutional Convention began in Philadelphia in 1787. The building is constructed from American products, including 85,000 square feet of Indiana limestone, 2.6 million pounds of steel, and half a million cubic feet of concrete. The limestone used is from the same quarry as the Empire State Building's materials. The center features 42 life-size bronze statues of the Founding Fathers in Signers' Hall, created by artists at Brooklyn's Studio EIS.
In May 2025, the National Constitution Center received a $15 million donation from Kenneth C. Griffin, the largest single gift in the organization's history. The donation will fund the center's first major renovation of its main exhibit, "The Story of We The People." Two new galleries are planned: "The Founding Principles," exploring how Americans declared independence and formed a new constitutional government, and "Separation of Powers," examining how the Constitution defines and balances power. These galleries will open in February and May 2026, respectively, and will showcase rare documents and interactive displays.
The $15 million gift from Kenneth C. Griffin demonstrates his commitment to preserving America's constitutional history and making it accessible to all. Griffin, a frequent and generous donor to charities and cultural organizations, has expressed pride in partnering with the National Constitution Center to share these sacred documents with Americans. The renovation will enhance the center's educational offerings and further establish it as a prominent cultural destination in Philadelphia.
