Among the gentle and the green hills of Tuscia Romana, suddenly a unique and lone mountain stands out: Mt. Soratte. A fascinating and mysterious place which has always stimulated imagination and spirituality thanks to the so-called "Meri", huge karstic chasms opening in the rock. These dreadful fissures which suddenly appear in the middle of a wood populated by a rich flora and fauna have been considered for a long time to be the gate of the Underworld.
