The name means "My folly" in French. The larger house is unusual in being composed of two parallel one-story structures joined by a roof.[2]

The house was headquarters of a Brazilian astronomical expedition in 1882 which studied a transit of Venus. The area has been said to have "an excellent panoramic view".[2]
