With the addition of the Barnes and the possibility of a new Calder Museum, Philadelphia’s Franklin Parkway might indeed become a long-envisioned grand arts boulevard. “The Parkway, of course, already has a lot going for it. The area is home to the Art Museum, the Rodin Museum, the Free Library, the Franklin Institute, the Academy of Natural Sciences, and Moore College. But there are huge gaps along the broad, tree-lined boulevard that make it hard for visitors and natives alike to think of the 1.1 miles from LOVE Park to the Art Museum as an entity.”
