Semiquincentennial Congressional Time Capsule Act

This law establishes a special congressional time capsule to commemorate the 250th anniversary of the Declaration of Independence. The Architect of the Capitol is required to create and bury this time capsule in the Capitol Visitor Center on or before July 4, 2026.

The time capsule will contain a joint letter from congressional leadership, along with other contents that Congress determines should be included. This allows current members of Congress to communicate directly with future generations and preserve items they deem historically significant for the nation's 300th anniversary.
