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. The subterranean structure is shrouded in mystery, from the discovery of elongated skulls to stories of paranormal phenomena. But the characteristic that has been attracting experts from around the globe is the unique acoustic properties found within the underground chambers of the Hypogeum.
Hal Saflieni Hypogeum is a cultural property of exceptional prehistoric value, dating back approximately 5,000 years and the only known example of a subterranean structure of the Bronze Age. The ‘labyrinth’, as it is often called, consists of a series of elliptical chambers and alveoli of varying importance across three levels, to which access is gained by different corridors. The principal rooms distinguish themselves by their domed vaulting and by the elaborate structure of false bays inspired by the doorways and windows of contemporary terrestrial constructions.
