Independence National Historic Park ~ http://www.nps.gov/inde
Independence National Historical Park, located in downtown (called "Center City"), Philadelphia, is often referred to as the birthplace of our nation. At the park, visitors can see the Liberty Bell, an international symbol of freedom, and Independence Hall, a World Heritage Site where both the Declaration of Independence and the U.S. Constitution were created. In addition, the park interprets events and the lives of the diverse population during the years when Philadelphia was the capital of the United States from 1790 to 1800. A section of the park where Benjamin Franklin's home once stood is dedicated to teaching about Franklin's life and accomplishments. Spanning approximately 45 acres, the park has about 20 buildings open to the public.
