1. Historic Philadelphia
No city in the country comes close to Philly when it comes to Revolution-era history. We’ve got Independence Hall, where the Declaration of Independence and Constitution were hotly debated and signed, and the Liberty Bell in all its cracked-up-the-side glory, which rang in 1776 to alert citizens to the first public reading of the Declaration. Dive deeper into the fight for independence at the Museum of the American Revolution, which houses George Washington’s actual army tent, and learn all you need to know about the Constitution at the National Constitution Center. Not in the mood for museums? You can still get a feel for this city’s history with ultra-passive endeavors, like visiting Benjamin Franklin’s grave at Christ Church Burial Ground or strolling down the oldest—and oh-so-adorable—Elfreth’s Alley, the oldest continuously occupied street in America. It looks just like it did back in the 1700s, with cobblestone streets and tiny thatch-roofed houses, some of which you can explore.
