Fodor's Expert Review Eglise Saint-Germain

This pristine 15th-century sanctuary served as a Protestant temple, a butcher's warehouse, a foundry, and a government meeting hall before Napoléon's troops returned it to Catholicism in 1803. The second chapel on the left maps a structural lineage that began in AD 400, and the steeple dates from the 14th century. Today's whitewashed walls, strategic lighting, and stained glass frame weekly classical music concerts in summer. Attending a concert or a service (the latter occurs at 10 on Sunday) is usually your only chance to see the inside.
