Grand Saint Paul

A Paris shop named in Marie's list of the shops the family has toured on 1874-05-16 (019.0229): «Quand je pense où nous avons été au Louvre, au Bon Marché, au Petit Saint-Thomas, au Grand Saint-Paul, à la Tour Saint-Jacques, au Nez rose, à la Cheville tournée !!!» The Louvre, the Bon Marché and the Petit Saint-Thomas are real department stores (Grands Magasins du Louvre opened in 1855; the Petit Saint-Thomas dates from 1830: Wikipedia); the last names of the list read as jokes. No shop called "Grand Saint-Paul" was found in the sources searched, so whether this is a real store or one of Marie's jests is not settled.
