Thanks to the immense wealth of its family, Maria de Médecis (also owner of a bank with branches all over Europe) bought the lands where there was a convent (not easy to remove) to expand the gardens. However, the maximum extent of them was not until 1792.
Haussman, who reconstructed the whole city adding big avenues and destroying complete neighbourhoods, divided the park in several points in order to construct his boulevards although neighbourhoods didn’t agree (the garden had open a few times for the public).
The palace and the gardens too suffered the vicissitudes of the owners and they were abandoned several times. The palace was transformed in prison when the French Revolution begun. During the Second World War German people used it as an encampment and they built a bunker in the garden.
