The Initiation Well of Sintra
In a garden in Portugal, a well that never held water spirals nine levels down into the earth. Many believe it was built for secret rituals.
What was reported
Quinta da Regaleira is a palace and garden in the hills of Sintra, built in the early 1900s for António Augusto Carvalho Monteiro, a wealthy collector with a passion for mysticism. Its gardens are full of grottoes, towers and tunnels.
Its most famous feature is the Initiation Well: a shaft 27 metres deep with a spiral staircase winding down past nine landings to a compass-star set into the floor at the bottom. Tunnels lead from the bottom out into the gardens.
Explanations offered
The well was never used for water. Many believe it was meant for initiation rites of the Freemasons or Knights Templar, and its nine levels are often linked to the nine circles of Dante's Inferno. No record says how, or whether, it was actually used.
