520 Chestnut St, Philadelphia, PA 19106, USA
Prior to being rechristened as Independence Hall, this building was used and known as the Pennsylvania State House. The founding fathers of the United States met here in the Assembly Room to debate and adopt both the Declaration of Independence and the United States Constitution. For a time the building fell into disrepair, but an 1824 visit from the Marquis de Lafayette (who had served as a soldier under George Washington) compelled the city to rescue and preserve this historic site. Entrance to Independence Hall is by guided tour only; tickets are required from March through December, but no tickets are needed in January or February. Fun fact: For a short time, the basement served as the city’s dog pound!
