The Initiation Wells (also called initiatic wells or inverted towers) are two wells on the property that better resemble underground towers lined with stairs. These wells never served as water sources. Instead, they were used for ceremonial purposes that included Tarot initiation rites.
The construction of the current estate commenced in 1904 by a man named António Augusto Carvalho Monteiro, and much of it was completed by 1910.
