In the heart of our planet's sprawling history lies a time shrouded in mystery, a period so ancient that it precedes our earliest recorded histories.

Pre-Historic Megastructures is a journey back to these obscured epochs, an expedition to uncover the remnants of civilizations that flourished before the great deluge known to many cultures.

Our exploration is driven by a profound question: What secrets lie buried in Earth's depths, awaiting rediscovery? As we peel back the veil of history in this almost 500-page book, we showcase over 30 pre-historic megastructures with images that defy easy explanation. These ancient sites, scattered across the globe, challenge our understanding of human history and beckon us to consider civilizations that may have thrived in a world vastly different from the one we know.
