Estufa Fria & Eduardo VII Park

This place carries memories of an abandoned quarry transformed into one of Europe's most ingenious botanical gardens, where wooden slats replace heating systems to shelter exotic plants from around the world. The Estufa Fria in Eduardo VII Park began as a 19th century basalt quarry. When workers struck an underground water stream, quarrying stopped and the site was abandoned. Local gardeners noticed plants thriving in the shaded, naturally humid pit.

Architect Raul Carapinha saw something extraordinary: a chance to build a greenhouse without mechanical heating. In 1933, he opened the Estufa Fria, meaning "Cold Greenhouse," where wooden slats regulate temperature naturally. The 1.5 hectare complex houses three distinct gardens. The original Estufa Fria displays temperate species including azaleas and camellias.

The Estufa Quente, added in 1975, recreates tropical conditions for coffee plants and exotic blooms. The Estufa Doce showcases over 300 varieties of cacti and succulents. Waterfalls, lakes and winding paths connect these living collections. Architect Francisco Keil do Amaral redesigned the surrounding park in 1945, creating the geometric hedges and Portuguese stone walkways. The 26 hectare park was renamed in 1903 to honor King Edward VII of Britain, whose visit strengthened the longstanding alliance between the two nations.
