Looking west from inside Central Park toward the buildings that line Central Park West.  ETA: As pointed out by batty’s comment, I believe the building is The Dakota, an apartment building at 72nd Street and Central Park West.  The Dakota is most recently known as former home to John Lennon and the site of his murder.  Yoko Ono is known to still have an apartment here.
