This site looks ancient but it's actually a 20th Century villa that was constructed in the early 1900s.
The aesthetic harkens back to a much earlier age with its stonework mimicking old castles of the region and extensive layout filled with unique (and sometimes hidden) features.
This spiral staircase on the site descends into "The Initiation Well," a structure nearly ninety feet deep with no clear purpose. The number of esoteric and alchemical symbols incorporated into the Quinta inspires speculation that this, and other areas, may have been used for occult practices.
At the base, where you see the pink compass, you come to a cave with a series of tunnels that lead out of the space...eventually.
