Leaving Notre Dame and turning right, we can see the corner of the cathedral and part of the Rue du Cloitre Notre Dame. Today we were not going that direction, but did a 180, and walked along the edge of the square.
On our left is the square in front of Notre Dame, and on the right is the Hotel Dieu (House of God), or hospital. There has been a hospital somewhere on this square since the Middle Ages.
Here's the front entrance to the Hotel Dieu. Over the arch is the legendary "Liberte Egalite Fraternite" from the Revolution.
At the far end of the cathedral square, we turned right along the Rue de la Cite. We've gone about half a block, and are looking across the street down the walking street, Rue de Lutece, to the Palais du Justice where the amazing Gothic Sainte Chapelle is located. You can't see any of it in this photo. On the left is the Prefecture de Police, and on the right is an area called the Place Luis Lepine, but is better known as the bird and flower market. The large building on the right is the Tribunal de Commerce.
This is the bird and flower market from the outside. We were on a mission, and didn't wander through it. The dome in the background is that of the Tribunal de Commerce.
