Desciption and image from Fine Art America (10 World Staircases | featured R O'Brien):  "This winding stone staircase can be found at the palace known as the “Palace of Monteiro the Millionaire”, from the nickname of its first owner, Antonio Augusto Carvalho Monteiro. The two Initian wells, descend into the ground like underground towers lined with stone stairs. These wells do not serve as water sources, but were actually for recreational use, to connect to various caves or monuments around the park.“
