Malta Hypogeum Features World's First Acoustic Chambers. Carved entirely by hand into limestone more than 5,000 years ago, predating Egypt's pyramids and Stonehenge Descends through three levels reaching about 11 meters below the surface Upper level contained remains of over 7,000 individuals
The Ħal Saflieni Hypogeum in Malta, dating to 4000–2500 BC, was roughly contemporaneous with Egypt's pyramids and Stonehenge. The three-level subterranean structure carved into globigerina limestone reaches about 11 meters below the surface. The Oracle Room is famous for remarkable acoustic properties where a male voice at 110 hertz causes the entire 3-level complex to vibrate. 🔊
