The owner of Quinta da Regaleira, António Augusto Carvalho Monteiro, was a known Freemason, and with the help of Italian Architect Luigi Manini, set about designing and constructing the four hectare estate with its enigmatic buildings, parks and tunnels which are laden with symbols related to alchemy, Masonry, the Knights Templar, and the Rosicrucians. There are obvious Hermetic/Rosicrucian connotations in the well:
“That which is Below corresponds to that which is Above, and that which is Above, corresponds to that which is Below, to accomplish the miracles of the One Thing” - Hermes Trismegistus
The well is divided in nine platforms reminiscent of the Divine Comedy by Dante and the nine circles of Hell, the nine sections of Purgatory and the nine skies which constitute Paradise. At the base of the well you will find a Rosicrucian Cross, which also happened to be the coat of arms of Carvalho Monteiro.
