Eminently street and participatory route. We will walk the thin line between myth and reality, the unusual and the hidden, the traditions and the popular heritage. We will visit three altars: a masonic altar, a magic altar and a fascist altar, but all of it peppered with the anecdotes of the city. Were the Knights of the Holy Sepulcher of Jerusalem in Barcelona? Are there pregnant virgins in Plaza Catalunya? Is there a house dedicated to the devil in the city? Where did Estruch de Sacanera, the magician, reside? What is the god that never sleeps in Barcelona? All these and many other questions will be answered in "Barcelona en Clave de Misterio." A Tour of the Hidden Path of the City.
