L'éscalier

I liked this staircase so much, I took 30 pictures of it!
It's in the Petit (keeping in mind that everything
is relative) Palais—where there were lots of beautiful
things to see and not a lot of people, so I
could actually see them.  There's also a very 
nice café, they don't mind if you take 
photos, and admission is free.
