The Alchemical Caves of Turin

[Paul Ferguson]

"Their location is known only by three people all over Europe, who know each other and who do not disclose it to anyone. Three caves, three portals, only three people know the secret, three like the vertices of a triangle, the three as the number of the trinity., a true and fascinating mystery. Over the centuries the hypothesis has been handed down that these portals can be found in the basement of Palazzo Madama or Piazza Castello or perhaps in the Royal Gardens. Elements to support these theses? Almost no one."
