Arboretum Marcel Kroenlein

The Arboretum Marcel Kroenlein, also known as the Arboretum de Roure, is a high-altitude arboretum situated 1,270 to 1,700 metres above sea level. It covers 15 hectares on the edge of the Mercantour National Park in Roure, Alpes-Maritimes, Provence-Alpes-Côte d'Azur, France. It is open daily.

The arboretum was conceived in 1987 when Michèle Ramin, now the arboretum's president, met Marcel Kroenlein, then director of the Jardin Exotique de Monaco. Its first trees were planted in 1988, and in 1989 artists began to display their artwork on the site. Featured artists have included Arman, Folon, Ben, and César. Every year the arboretum organizes an exhibition sponsored by a contemporary artist; examples include: Andy Goldsworthy and Ousmane Sow.
