Philadelphia, which is one of the historic cities in America, is the ideal place to spend a weekend - preferably a fairly lengthy. Be sure to look at the Liberty Bell and Independence Hall, where the Declaration of Independence was signed and the US Constitution. Both of these attractions are part of Independence National Historical Park. Philadelphia also boasts several famous art museums, including the Rodin Museum. Franklin Institute Science Museum is one of the many attractions associated with the name of Benjamin Franklin, the famous inhabitant of the city. After so much historical information, make sure that there is room for a classic steak sandwich "Philadelphia."
