The Secret Castle: The Key to Good and Evil
by Miguel Bronchud
This book starts in the ancient Castle at Mora De Rubielos, in Spain. This Castle has a XIIIth century winding staircase, leading to the dungeon, with secret Masonic symbols engraved on the vertical side of most steps and on the walls. The author made attempts to save the stairs (and the engravings) from the destruction of time and wear, but also to understand the meaning of these symbols.
