The tourist office of Poitiers has a simple idea, but a great one: just follow the lines! From the magnificent church of Notre Dame la Grande in the center, there are three pedestrian routes that you can follow around the city. On the ground there are three colored lines for three tracks: the blue line leads to the old neighborhood with the Episcopal church with Sainte Radegonde and main road (Grand Rue). The yellow line from Notre Dame, will lead to another neighborhood, the church of Saint Jean de Montierneuf. And finally, the red line, perhaps my favorite, leads to the church of Saint Hilaire (there are many churches in Poitiers!) which is usually full of Compostela pilgrims.
