Join us at Gateway Arch National Park to celebrate Constitution Day and Citizenship Day! This annual federal observance commemorates the signing of the U.S. Constitution on September 17, 1787.

We invite you to participate in a special event at the entrance to the Museum under the Arch. The event will include hands-on crafts and activities for visitors of all ages, including coloring pages and paper hat creations. These activities will provide a creative opportunity for you to share what the Constitution means to you.

Come honor this historic document and reflect on the values it represents. Activities are free and open to the public. We look forward to seeing you there!
