The primary use of the Chateau is to speed the French along their road to a cultural victory. Tourism can be generated based on the Culture of Chateaux with a Hotel, Airport, and/or a National Visitor Center. As an added benefit, your army may use Chateaux to defend your lands from invasions.
You should plan well where you intend to construct Chateaux. Since they don't cost Gold, you can build as many as you want wherever you can. Still, positioning a Chateau strategically may also help you to defend your lands and/or position another Chateau or another improvement nearby.
A chateau is a manor house or country home of gentry, usually without fortifications. In the Middle Ages, a chateau was largely self-sufficient, being supported by the lord's demesne (hereditary lands). In the 1600s, the wealthy and aristocratic French lords dotted the countryside with elegant, luxuriant, architecturally refined mansions such as the Chateau de Maisons. Today, the term chateau is loosely used; for instance, it is common for any winery or inn, no matter how humble, to prefix its name with "Chateau."
