Announcing the official release of Teaser Trailer #1 for The Missing Key documentary! 🎥🔥
I’m joined by legendary geologist Dr. Robert Schoch, dive expert Tahsin Ceylan, and a team of archaeologists, researchers, and sacred-geometry experts as we travel across the world to explore some of humanity’s greatest unanswered questions. 🔎
From the extraordinary underwater ruins of Lake Van, Turkey, to the Great Pyramids of Giza, the Andes Mountains of South America, and the jungles of Cambodia, evidence of a forgotten chapter of history is emerging—one that may change everything we know about our past. ⏳
Releasing Q4 of 2027!

Announcing the release of my NEW Podcast!
Join me, Matthew LaCroix, for the launch of my new flagship series: The Lost Civilizations Podcast!
Together, we journey across the ancient world to investigate lost sites, megalithic stonework, ancient knowledge, and forgotten chapters of human history—following the evidence and unanswered questions that may reshape how we understand our past.
Each episode explores new locations, discoveries, and ancient traditions as we search for clues to the civilizations and knowledge lost to time.
Available on Spotify, Apple Podcasts, and YouTube!

I’m proud to announce the release of the ACD — the Ancient Code Database! 🔎
After three years of field investigations and tracking this ancient code from Peru and Bolivia, through eastern Anatolia, ancient Egypt, India, and the jungles of Cambodia, I’m excited to finally release this global database to the world.
Although many of these connections and meanings were explored in my book, The Missing Key, there has never been a global database cataloguing and clearly displaying this entire system in one place.
The ACD brings these worldwide connections together for the first time, while also providing a complete definition index explaining the recurring symbols, cosmograms, relationships, and meanings behind them.
After spending years investigating these sites around the world and studying this remarkable corpus of symbols, I believe I have cracked this important ancient code. 🧩
