Philadelphia is not the most good looking city in the US but if you go over the gray buildings, the Rocky statue and the dubious culinary specialties, there are hidden treasures at the corner.

For a long time Philadelphia was the most important city of the United States, going as far as to become the capital when Washington was under construction. There are many historical vestiges that attract American tourists but the most attractive thing is surely the museums. The Philadelphia Museum of Art is one the most important museum in the US and the Barnes Foundation is an amazing collection of impressionsim and modern art paintings.
