 The greenhouse underwent a remodeling that accompanied the remodeling of Parque Eduardo VII, with the construction of the lake at the entrance and a huge living room, the ship call, which hosts several types of events.In 1975 two new sections opened, the Estufa Quente and Estufa Doce, expanding the botanical collection to include plants from the tropics and equatorial species.The term "cold greenhouse" comes from not using any heating system.
