This tiny shrine in the shadow of Notre-Dame is one of the three oldest churches in Paris. Founded in 1045, it became a meeting place for university students in the 12th century and was Dante's church of choice when he was in town writing his Divine Comedy. Today's structure dates mostly from the 1600s, but keep an eye out for older pillars, which crawl with carvings of demons. You can maximize your time inside by attending one of the classical or gospel concerts held here. Alternately, go outside and simply perch on a bench in the garden to relish the view of Notre-Dame.
