Expensive Mansion, Toronto, Canada

The uses of these edifices paralleled that of the Roman villas. It was vital for powerful people and families to keep in social contact with each other as they were the primary moulders of society. The rounds of visits and entertainments were an essential part of the societal process, as painted in the novels of Jane Austen. State business was often discussed and determined in informal settings. Times of revolution reversed this value. During its revolution, France lost a large part of its country homes to incendiary committees, who destroyed the estates as a reaction to/rejection of the ancient régimes.
Until World War I it was not unusual for a moderately sized mansion in England such as Cliveden to have an indoor staff of 20 and an outside staff of the same size, and in ducal mansions such as Chatsworth House the numbers could be far higher. In the great houses of Italy, the number of retainers was often even greater than in England; whole families plus extended relations would often inhabit warrens of rooms in basements and attics. It is doubtful that a 19th century Marchesa would even know the exact number of individuals who served her. Most European mansions also were the hub of vast estates. A true estate (the medieval villa, French ville) always contains at least one complete village and its church. Large estates such as that of Woburn Abbey have several villages attached.
Nineteenth century development
The 19th century saw particularly in the United States a new type of mansion being built, often smaller than the older European mansions. The Breakers in Rhode Island is a fine example, as is the nearby, but completely different, Watts Sherman House.
