An Initiation Well is a structure often found in mystical or spiritual contexts, particularly associated with the Order of the Templars and Freemasonry. These wells are typically deep, circular shafts that symbolize a journey into the subconscious or a rite of passage. They are designed to evoke feelings of introspection and transformation. One of the most famous initiation wells is located in Quinta da Regaleira in Sintra, Portugal. This well features a spiral staircase that descends into the earth, representing a descent into the depths of knowledge and enlightenment. The design often incorporates various symbolic elements, reflecting the beliefs and practices of the groups that use them.
