Less impressive building, located next to the Independent Palace. But it was the early Congress of the United States. It is part of the Historic Park and is now free to visit. But I wasn't open when I went.
When the United States became independent, Philadelphia served as a temporary center. The parliamentary chamber is also here.
I remember that this is free, when the Haihang Newspaper Group went to Philadelphia on the way to visit, like a group of 10 people, and then the official will give you a guide, but the whole process is in English.
