Sacred, or holy, places are spaces or objects that are revered. From ancient times, humans have imbued the surrounding world with divine meaning. Sacred places became hosts to the supernatural, inhabited by deities and ancestral spirits, becoming temple centers. Sacred sites played a key role in shaping the self-awareness of peoples, linking them to the divine world. Objects of sacred archaeology, geography, and cultural studies are archaeological, historical, geographical, religious, and natural-cultural sites and heritage monuments where one can find and reconstruct ancient knowledge on sacred history, geography, religion, mathematics, astronomy, metrology, and other ancient branches of priestly "science". Göbekli Tepe, Stonehenge, the Ziggurat of Etemenanki in Babylon, the Palace of Knossos, the Temple of Hera on Samos, the Delphic Temple, the Dodona Oak, the Parthenon of Athena Pallas... The next book in the series tells about the hundred most famous sacred places of the Ancient World.
