The Arboretum de Versailles-Chèvreloup is an arboretum located in Rocquencourt, a French commune just north of Versailles. It is part of the National Museum of Natural History in Paris. This park, covering 200 hectares, is a real tree museum: it presents and preserves about 15,000 different species and varieties of trees from all over the world. It also constitutes a study and research center for biologists, botanists and geneticists and makes sources and references available to them. The history of the arboretum goes back to 1699, when Louis XIV bought the land to extend the park of the royal palace of Versailles.
