Estufa Fria

The greenhouse was remodeled concurrently with Eduardo VII Park in 1945 by Portuguese architect Francisco Keil do Amaral.

On 29 April 2009 the original Estufa Fria closed due to the risk of collapse of its steel structure.

[3] Measuring 1.5 hectares (3.7 acres) in area, the Estufa Fria consists of three parts: The term "cold greenhouse" comes from the original building's lack of mechanical heating; instead, wooden slats regulate sunlight and protect the plants from excessively hot or cold temperatures.

[4] The Cold Greenhouse is the largest of the three, measuring about 8,100 square metres (87,000 sq ft) in area.

The Estufa Quente occupies about 3,000 square metres (32,000 sq ft) and is home to tropical species such as coffee and mangifera.
