The Hypogeum of Hal Saflieni in Malta is a UNESCO World Heritage Site which is believed to be the oldest prehistoric underground temple in the world.

Thewhole site is shrouded in mystery, from the discovery of elongated skulls to stories of the paranormal.

The main uniqueness about this site though is its characteristics, and it has been attracting experts from around the globe for years. It has unique acoustic properties and although not known for certain, it is believed that the hypogeum was originally used as a sanctuary, possibly for an oracle. It is for this reason that a unique chamber carved out of solid limestone and demonstrating incredible acoustic properties has been called ‘the Oracle Chamber’.

According to William Arthur Griffiths, who wrote ‘Malta and its Recently Discovered Prehistoric Temples’, a word spoken in the Oracle room is “magnified a hundredfold and is audible throughout the entire structure.” It is said that standing in the Hypogeum is like being inside a giant bell. At certain pitches, one feels the sound vibrating in bone and tissue as much as hearing it in the ear. The questions remain. was it intentional? Was the Hypogeum actually designed to enhance amplification? If so, why? Is it possible that the designers of these spaces knew something that modern scientists are just rediscovering now?
