This "view from Sacre Coeur" is taken from the dome -- not quite the top, but purt'near...  That is, of course, the Eiffel Tower to the left.  I believe the structure to the right is the Grand Arch of La Defense.  And, yes, that is the roof line of the church along the right margin.  Got vertigo?
It's 386 steps from the crypt to the dome (puff puff pant!) and I was pretty shaky by the time I got up here.
