The Hypogeum of Ħal-Saflieni is a subterranean structure dating to the Saflieni phase (3300-3000 BC) in Maltese prehistory, located in Paola, Malta. It is often simply referred to as the Hypogeum (Maltese: Ipoġew), literally meaning "underground" in Greek. The Hypogeum is thought to have been originally a sanctuary, but it became a necropolis in prehistoric times, and in fact, the remains of more than 7,000 individuals have been found.
