Outside, Louvois had extensive hydraulic works to power the waterways of the park, and allow the most spectacular water jets. The upper park was developed, while Le Notre worked on the gardens continually throughout the 1680s and created practically all of the lower gardens, invented new groves and parterre, including the one in front of the Grotto. Louvois also arranged a large vegetable garden along the avenue of the castle, in order to meet the needs of the castle, a vegetable garden which would later be called "the vegetable garden of the Dauphin". In short, he builds everything at Meudon that Louis XIV did in a more spectacular way still at Versailles at the same time. And he asked Israel Silvestre, drawing master of the Louis de France to engrave the entire estate, which Silvestre carried out with several very spectacular prints, among the most careful of his work.
