the Passage Pommeraye is a small shopping mall in central Nantes, France, named after its property developer, Louis Pommeraye. Construction started at the end of 1840 and was completed on 4 July 1843. The Passage Pommeraye is a passage between two streets, with one 9.40 m higher than the other. Midway, there is a flight of steps and the mall then continues on another floor. Two architects, Jean-Baptiste Buron and Hippolyte Durand Gasselin, contributed to its design, which is very elaborate and includes renaissance style sculptures. The Passage Pommeraye has been classified as a historic monument since 1976. (Wikipedia)
