Palacio de Cristal greenhouse in La Arganzuela

In 1992, the facilities of this greenhouse were opened to the public. It contains nearly 1,200 plant species belonging to 100 families, divided into four areas: subtropical, tropical I and tropical II, and cacti and succulents, with rare specimens and an outstanding orchid collection. The itineraries are very well organised, and a brochure provides assistance in locating plants.
