An ancient stone temple and burial site built around 3,300 to 3,000 BC. Inside the small square oracle chamber of the underground temple of Hal Savlieni the building's smooth stone walls reflect and resonate sound. This Neolithic underground structure carved into limestone three levels deep was discovered in 1902. The underground structure replicates the above-ground temple by excavating deep below. The middle-level chamber possesses acoustic properties capable of reflecting low-frequency sounds approximately 111 Hz which affect human brainwaves.

The beginnings of human civilization the transition to permanent settlements the construction of houses agriculture and animal husbandry are enigmatic. A 5,000-year-old prehistoric terracotta statue in Malta "The Sleeping Woman" or Venus of Malta is considered one of the rarest Neolithic artifacts to retain its beautiful form. The use of polished stone typical of the Neolithic period basket weaving and the development of traditions and burial sites are also significant clues. They built houses close together in villages near water sources.
