Rue Vieille du Temple. This neighborhood website introduces you to a 13th century street in the Marais. The map is not interactive but the buildings' history and some of the anecdotes are interesting. The best part is that you get to see pictures of the residents and, if you understand French, can read a bit about the gentrification of the area. [ul]
