Veritas, The square that Orio refers to is "Square Marice Gardette." It's the park area above and to the left of your yellow circle. The address "6" would put E-on a bit further north, closer to "Passage Guilhem." The intersection of "Rochebrune" and "Gen. Guilhem" has the address "1." The intersection of "Gen Guilhem" and the street to the north and directly below "Rue Saint Amboise" ("Rue Lacharriere") has the address "13." Somewhere in the middle would be my guess. This is a sad time for France. Violence in Paris hurts deeply. Truth
