4 Best Sights in Bordeaux and the Wine Country, France

This handsome château, which dates from 1723, reveals many layers of history, starting with a typical Gallo-Roman residence and a medieval citadel. The Salle des Gardes's medieval walls were incorporated into the newer building and a restored 13th-century pigeonnier can be viewed on the château grounds. The château museum displays lively carrousel horses and a tip-top collection of antique carriages and other conveyances.

Overlooking the Garonne River in the very heart of town, Cadillac's château was built by the first Duke of Épernon (1554–1642) as a family seat befitting his wealth and influence. The duke's son fell afoul of Louis VIII when he refused a military assignment and was sentenced to death in absentia (he had already fled to England). Seized during the French Revolution, the Renaissance-style château served as a women's prison and psychiatric hospital until the 1950s. The stately home's lovely contours, ornate fireplaces, and 17th-century tapestries make it well worth a visit.

Although several estates in and around Blaye offer tours and tastings (all listed on the Tourist Office website), the Château Marquis de Vauban is one of the best with comprehensive explanations of the winemaking process, wine tastings, tours of the vineyards and citadel, and fine dining.
