This museum is located adjacent to where Benjamin Franklin's house once stood back in the 1700s, and is taking up residence in the Independence National Historic Park. The museum is 20,000 square feet and underground. The exhibits and museum store are underground as well. To get visitors in the appropriate mind set, before the museum entrance is the Benjamin Franklin Ghost house. Above ground, this ghost house is a steel structure designed by architects to trace outlines of Franklin's old house and his old printing shop. Established in 1976, the museum has gone through a massive upgrade within the last two years and reopened to the public in August 2013.
