Philadelphia is associated with America250’s planned time capsule and 76-tree project.
The city was central to the American founding. The Second Continental Congress met in Philadelphia, and Independence Hall is the historic site most closely associated with the adoption of the Declaration of Independence in 1776.
For the 250th anniversary, Philadelphia planned a time capsule to be buried on July 4, 2026 and opened on July 4, 2276. The city also received support for planting 76 commemorative trees at Independence National Historical Park, with the number recalling 1776.
Philadelphia is sometimes confused with Washington, D.C., because the capital hosts many national celebrations and monuments. However, Washington became the permanent national capital decades after independence. Philadelphia’s America250 role rests on its Revolutionary-era history.
