Estufa Fria

This guide to Estufa Fria in Lisbon follows how a flooded, abandoned basalt quarry became one of the city's strangest gardens, after the painter and architect Raul Carapinha saw a natural greenhouse in the ruined pit. You'll hear how the wooden-slatted roof, finished in 1933, keeps the garden cool without glass or heating, and about the camellias, tree ferns, and coffee and mango trees now growing where quarrymen once drilled for stone. Walk deeper in for the coolest, shadiest corners.
