One of the earliest references to Furnas came from the harvesting of trees in the valley of Furnas, in order to assist the construction of many of the homes destroyed by the 1522 earthquakes and landslides in Vila Franca do Campo. This includes numerous trees used to rebuild the parochial church, a project begun by Donatary-Captain Rui Gonçalves da Câmara. In 1553, his predecessor Manuel da Câmara, issued an edict to re-plant these trees after the area was nearly deforested, and roadways were expanded under his son, Rui Gonçalves da Câmara, in order to develop the area, allowing cattle herding in the valley after 1577.
