I really love this church! Although it is not as famous as Notre-Dame, I find it beautiful and love how the steps are covered in flowers during the spring/summer. I often grab a sandwich and eat it on the steps, as you have a view down Rue Royale and onto Place de la Concorde. Entrance is free so in the summer it's a good place to cool off.
A grand building that I have passed several times in my time in Paris but have yet to go inside.
beautiful and magnificent
