This section for the Hypogeum is called the Holy of Hollies and is the most important and by far the best Architectural ornate room in this labyrint.
The Hypogeum is an enormous subterranean structure excavated c. 2500 B.C., using cyclopean rigging to lift huge blocks of coralline limestone. Perhaps originally a sanctuary, it became a necropolis in prehistoric times.
