So, in Montparnesse there are the catacombs, I thought this was an interesting place. And if you have not been, take the subway to the Pere Lachaise Cemetery. Both of these places is why I want to return to Paris, mainly to photograph more (need tripod in the catacombs for better photo's).

Also in that area (near the catacombs) is a street full of reasonably prices shopping (shoes etc) and a food street (I think pedestrian, but can not remember). We just walked around that area but I think this stuff was west of the catacombs.
