Following our experience gained from previous expeditions, we applied our archaeoacoustic technique (SBRG protocol) to look at an interesting question relating to the town of Alatri in Italy. At the highest point of the town there is an ancient acropolis and by archaeoacoustic methodologies we wanted to research if there is an explanation to why there was a megalithic temple on top of the hill, on which was subsequently built the present Cathedral of Alatri. Some vibrations seem to arise from the geological fault placed on the side of the hill where the town was built in ancient times.These frequencies would have increased the effect of rituals by enhancing the psyche of the participants due to the influence of these low vibrations on human brain waves. This suggests the builders of the temple had some sort of knowledge of this effect and explains why the temple was built on that location.
