Estufa Fria



The Estufa Fria (lit. "Cold Greenhouse") is a greenhouse with three distinct gardens located in Eduardo VII Park between the streets Alameda Engenheiro Edgar Cardoso and Alameda Cardeal Cerejeira in Lisbon, Portugal.

History
The Estufa Fria opened in 1933. Portuguese architect conceived and designed the project. It was built near an old basalt mine which had been abandoned after a spring was discovered nearby. The greenhouse was remodeled concurrently with Eduardo VII Park in 1945 by Portuguese architect Francisco Keil do Amaral. The greenhouse's existing entrance porch, a lake near the entrance, and a large visitor "living room" called "the ship" or "the vessel" (nave) were built during this time.

Expansion
In 1975 the Estufa Quente and Estufa Doce sections opened, expanding the botanical collection to include plants from tropical and equatorial regions. On 29 April 2009 the original Estufa Fria closed due to the risk of collapse of its steel structure. It reopened in April 2011 after two years of renovation work.

Description
Measuring 1.5 ha in area, the Estufa Fria consists of three parts:


 * Cold Greenhouse (Estufa Fria)
 * Hot Greenhouse (Estufa Quente)
 * Sweet Greenhouse (Estufa Doce).

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. The Cold Greenhouse is the largest of the three, measuring about 8100 m2 in area. It is home to azalea and camellia species from around the world.

The Estufa Quente occupies about 3000 m2 and is home to tropical species such as coffee and mangifera. The Estufa Doce contains cacti and other succulent plants, such as aloe.

The entire greenhouse complex features small lakes, waterfalls, and sculptures. Some of the sculptures are by noted twentieth-century Portuguese sculptors, including, , and.
