Independence Hall, Philadelphia (must see)

By the late 1720s, Philadelphia realized it was running a colony with big decisions to make, but was lacking a proper stage to make them—so, naturally, it decided to build one.

Construction began in 1732 on Chestnut Street, guided by architect Edmund Woolley, and by 1753, the Colonial Government of Pennsylvania moved in without hesitation. For nearly half a century, this was where the business of the province—and later the commonwealth—was handled, until the capital duties packed up and moved on in 1799.

The building itself, now known as Independence Hall, keeps things elegantly symmetrical. Red brick, Georgian style, a central block crowned with a bell tower and a steeple rising 169 feet. Arcaded passageways link the main structure to its side wings, while nearby, Old City Hall, Congress Hall, and Philosophical Hall gather around Independence Square like a well-organized ensemble cast.

Inside, the layout is straightforward but loaded with history. The Assembly Room and Supreme Court Room sit on the ground floor, divided by a vestibule, with the Tower Stair Hall waiting just beyond the entrance. The interiors you see today are the result of careful restorations in the 19th and 20th centuries, all aimed at returning the building to its 18th-century look—because when your past includes founding a nation, you tend to preserve the décor...

And then, of course, came the moments. In June 1775, George Washington was appointed commander-in-chief of the Continental Army right here. A month later, Benjamin Franklin was named the first Postmaster General—arguably launching one of the longest-running institutions in American life. Between 1775 and 1783, this was the meeting place of the Second Continental Congress, where, on July 4, 1776, the Declaration of Independence was approved. Eleven years later, in 1787, the Constitution followed.

Since then, Independence Hall has remained more than just a historic building. It continues to serve as a backdrop for speeches, rallies, and protests—less a frozen monument, more an ongoing conversation about democracy, still very much in progress.
