Quinta da Regaleira - the tunnels beneath

Some footage from the (unexpected to me) tunnels under Quinta da Regaleira World Heritage Site garden in Sinitra, Portugal.

From Wikipedia
"Monteiro was eager to build a bewildering place where he could collect symbols that reflected his interests and ideologies. With the assistance of the Italian architect Luigi Manini, he recreated the 4-hectare estate. In addition to other new features, he added enigmatic buildings that allegedly held symbols related to alchemy, Masonry, the Knights Templar, and the Rosicrucians."

"The Initiation Wells (AKA 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 tunnels described above connect these wells to one another, in addition to various caves and other monuments located around the park. Of the two wells, the larger one contains a 27-meter spiral staircase with several small landings. The spacing of these landings, combined with the number of steps in the stairs, are linked to Tarot mysticism"
