Franklin Court is a series of buildings on the site where Benjamin Franklin's home once stood. In the front are the storefronts Franklin used for a printing office and post office, and in the courtyard is a "Ghost House" that outlines what Franklin's house would have looked like if it still existed. Also at this site is an underground museum about Dr Franklin. When I visited it was terribly outdated, but since then plans are underway to completely update the site.
