At dusk on Saturday, the Centennial Bell that hangs in the Independence Hall tower chimed for the first time in 18 months, filling the air with a clear, crisp sound that will mark every hour of every day.
About 100 bystanders gathered to watch the unveiling of the Philadelphia landmark.
"Here we are in the figurative shadow of our founders," Cynthia MacLeod, superintendent of Independence National Historical Park, said as she welcomed the crowd.
She described the history of Independence Hall, from the signing of the Declaration of Independence to the ratification of the Constitution. "Doesn't it look sublime?" she said of the newly renovated tower and clock.
