If there is a place permeated through and through with mystery, it is undoubtedly Prague. A city of magicians, alchemists, and initiates. A wondrous place said to lie on the border of two realities, a true threshold, a gateway to another dimension.

Long ago, a group of monks from India reportedly arrived, discovered the unique properties of the location, and built the first structures here to further enhance the ability to contact other worlds, especially the supernatural.

Author Dan Brown stated that his fascination with Prague "began with its deep history of mysticism and occultism. It is a labyrinth of mysterious places — the perfect setting for a Robert Langdon thriller — a city of secrets, both ancient and modern."

And indeed, in Prague, traces of fascinating secrets are hidden at nearly every step. Fragments of long-forgotten events, echoes of a past full of mysteries and unexplained moments. Arnošt Vašíček presents the nine greatest mysteries of the city where the secret of all secrets was born.
