A temple both below a limestone hill and beneath it too, the Hypogeum near Malta’s capital Valletta, dates back to either before Noah’s flood of 11,000 BCE or from before Thera erupted and killed Minoan hegemony in the eastern Mediterranean.
One large room in the Hypogeum, The Oracle Room, amplified sound a hundred times. People curled up in small rounded cubicles carved into the walls to listen.
The part of the Hypogeum Malta lets us see holds 30 rooms that passages, stairs and halls link. The builders cemented the walls with concrete of compacted rock dust and water. In the rooms, they smoothed the walls with imported flint instruments. [Coppens, 2012]
