An America250 time capsule is scheduled to be buried in Philadelphia on July 4, 2026.
Philadelphia is closely connected with the founding era: the Second Continental Congress met there, and the Declaration of Independence was adopted in the city in 1776. That historical connection makes Philadelphia a natural setting for a semiquincentennial time capsule.
The capsule is planned for burial at a site associated with the city’s Independence National Historical Park. Its scheduled opening date is July 4, 2276, exactly 250 years after the America250 observance and 500 years after the Declaration’s adoption.
This project is distinct from the national commission’s broader event planning. It is a local Philadelphia commemoration designed to leave material evidence of 2026 for people marking the United States’ next major anniversary.
