Time Out says
The most colourful of the capital's many parks, Montsouris was laid out for Baron Haussmann by Jean-Charles Adolphe Alphand. It includes a series of sweeping, gently sloping lawns, an artificial lake and cascades. On the opening day in 1878 the lake inexplicably emptied, and the engineer responsible committed suicide.
