Philadelphia is scheduled to receive the America250 time capsule buried for opening in 2276.
The planned capsule is connected to Philadelphia’s central place in the founding story of the United States. The city hosted the Second Continental Congress and was where the Declaration of Independence was debated and adopted in 1776.
Plans call for the capsule to be buried in Philadelphia on July 4, 2026, during the Semiquincentennial. Its scheduled opening is July 4, 2276, exactly 250 years later, when the United States would mark the 500th anniversary of the Declaration’s adoption.
Philadelphia is sometimes confused with Boston or Washington, D.C. because all three cities are closely associated with American history. Philadelphia, however, is the city specified for this America250 time-capsule plan.
