On this beautiful spring day in Philadelphia, I took a drive out to one of the potential sites for a Capital of the World — Belmont Plateau in Fairmount Park. It’s easy to see why Philadelphians offered this location to the United Nations. Notice the skyline of the city visible beyond the tree line. In 1945-46, the skyline would have been only as high as Philadelphia’s City Hall, but the trees would have been lower, too. The location also is within view of Memorial Hall, one of the few remaining structures from the Centennial Exhibition world’s fair in 1876. It was a spectacular offer, and it nearly lured the United Nations out of New York.
