If you love fine wine, you’ll love the twin villages of Tournon and Tain-l’Hermitage. Tournon may be a small town, but stirring events took place here: A castle was raised on the hilltop in the 10th century to protect the region, and new fortifications were added over the centuries, including two “new” towers built to defend against Protestant attacks in the 16th century. You’ll see the handsome houses constructed by wealthy merchants and garrison officers when you walk through the Rue de Doux area, and you’ll pass the 14th-century church and the oldest secondary school in France.
