Greenhouse and botanical gardens with an area of 7100 square metres, located inside the former municipal slaughterhouse in the district of Arganzuela, built by architect Luis Bellido y González between 1908 and 1928.

In 1992 it was restored and regenerated for use as a greenhouse, taking its inspiration from the nineteenth century greenhouses to be found in parks in many cities across Europe such as Vienna and London, representative examples of 19th century Cast-Iron Architecture.

Today it houses 9000 species of plants presented as four distinct and separate biotopes, each with its own microclimate with four categories of plants: tropical flora, subtropical flora, succulents and cactaceae, and aquatic plants. It is also home to a many species of fish.
