Robert Indiana's Love sculpture looking up the boulevard toward the Philadelphia Musuem of Art.
Looks kind of like a set on a Hollywood lot, but is in Center City Philly instead.
The gigantic pipe organ (only a small fraction of it is visible here) at the old Wanamaker's Department Store (now Macy's). They play the thing twice a day, but they never really open it up--I suppose so as not to disturb shoppers--so listeners have no idea what the instrument can really do. One day I will get there for an actual afterhours concert. The only way you can really appreciate the organ.
