Castles and châteaux, what is the difference?
The difference between a castle and a château lies mainly in the period when they were built. A castle is a fortified residence built mainly in the Middle Ages, whereas a château is a showpiece residence of the nobility, typical of the early modern period.
A castle is therefore considered the predecessor of the château. Castles mainly served defensive and residential purposes. Over time, some of them were rebuilt into residences that looked more like châteaux. Châteaux have lavish decoration and are magnificent buildings that served representative and residential purposes. They had no defensive role, so they have no fortifications at all.
However, not every country in the world distinguishes between the terms castle and château. In many languages, a large noble residence has a single name.
