Built to answer one question.
The research platform for ancient mysteries, combining the world's most comprehensive open-licensed database of ancient sites with geometry engines that test every pattern against chance, great-circle corridor analysis, documented archaeoastronomy with sources and AI-powered research tools.
Answers written in stone.
Our mission
We believe the ancient world holds answers we are only beginning to understand. Pyramason was built to give researchers, historians and curious minds the tools to test those answers: from the measured orientation of pyramids to the geometry between stone circles, from great-circle corridors spanning thousands of miles to the acoustics measured inside chambers.
Our mission is to make professional-grade archaeological research accessible to everyone, backed by legally verified open data, honest statistics and the latest in AI technology. Every pattern the map finds is tested against chance, and the map says so when chance wins.
Instruments of inquiry.
The research tools
The Living 3D Map
Explore 188,772 sites in a native 3D world with full terrain, atmosphere, and seamless zoom from orbit to street level.
Antiquity & Empires
Strip the modern world off the map, roads, borders and present-day labels, and raise 58 great cities of antiquity under their own names, with 16 civilisations drawn at their greatest extent. Free for everyone.
Documented Alignments
What archaeoastronomers have actually measured at 17 famous sites: 48 sourced entries, each tagged documented, contested, claimed or rejected, recomputed by the map for the site latitude and building epoch. Includes the Azimuth Identifier, the test a field surveyor runs. Free for everyone.
Gnomon Shadow
The shadow-tip track of a vertical rod for any place, date and epoch, drawn on the map at true scale. Equinox buttons reproduce the method that gave the Great Pyramid true north to within a few arcminutes. Free for everyone.
Sacred Geometry Analysis
Detect Golden Ratio (phi), Fibonacci chains, Pythagorean triangles and geometric patterns between ancient sites, each scored against an empirical chance baseline. Visualise grids and overlays in real time.
Great-Circle Corridors
The ley line hypothesis, tested. Draw corridors across multiple sites, see the true great-circle fit, the km tolerance and the p-value against a null model, with AI context on what is known about the sites along the line.
Mystery Decoder
Measures first, then speaks. Regional and worldwide famous sets run through the alignment engine with 2000 real-site null draws, three great-circle corridors, solstice, equinox and lunar standstill bearings to every neighbour within 30 km. Output: an evidence grade A, B, C or none, and a 120-word brief that may only quote the numbers. Pro.
AI Research Reports
Generate deep research reports on any site, powered by Claude AI, covering history, theories, measurements, cultural significance and scholarly debates.
Sky Align & Natal Charts
NASA-grade planetary positions back to 3000 BCE, epoch-aware obliquity and solstice azimuths computed from latitude, and natal wheels illustrated with original 1824 star atlas engravings.
Frequency Centre & Frequency Lab
Solfeggio, Schumann, binaural and custom tones with volume and a sleep timer, plus the Frequency Lab: documented chamber acoustics with sources, ancient tunings you can play, a sine sweep and a microphone spectrum analyser for measuring real rooms. Free for everyone.
Cymatics Lab
A real free-edge circular plate, Kirchhoff-Love theory with the Leissa 1969 frequency equation solved numerically, in aluminium, steel, brass, glass or titanium. Ten thousand sand grains settle on the nodal lines, and the eigenvalues are checked against the published table.
Platonic Solids
Project tetrahedra, octahedra and icosahedra onto the globe and count the sites near their vertices, checked against 200 random rotations. The orientation is arbitrary and the map says so.
Astral Projection Flight
Immersive first-person flight across the ancient world. Create custom waypoint paths, record cinematic flythroughs and export branded footage.
Cinematic Director
The map films itself. Ten shot templates, one ACTION button: the Director hides the interface, flies the scenario hands-free and records a finished clip, up to 4K. Built for content creators.
Connect Your AI
The living map speaks MCP. Paste map.pyramason.com/mcp into Claude, ChatGPT or any AI and ask it about 188,772 real places. Free for everyone.
Community & Research Projects
Annotations, forum, five real-time researcher channels, collections and a leaderboard that recognises the sharpest contributors.
Every site, traceable.
Our database and its provenance
Pyramason is built on a fully open-licensed database of 188,772 verified ancient sites, the largest legally sourced open dataset of its kind. Every site is traceable, citable and free of proprietary restrictions.

The story behind Pyramason
What if the people who built the pyramids, the stone circles and the great temples knew something we have forgotten? Not mythology. Not superstition. Something measurable, geometric, encoded in stone.
My fascination with the ancient world didn't start in a lecture hall or a library. It started with that question, and I couldn't shake it. I'm not an archaeologist. I have no formal coding background. What I had was curiosity, stubbornness, and a conviction that the right tools could help answer it. In November 2024 I started building Pyramason from scratch, learning to code through AI-assisted development, piecing together a platform that combined maps, data and research tools in a way that didn't exist anywhere else.
Every feature on this platform was built because it asked a genuine research question. Sacred geometry analysis, because the proportions kept appearing across unconnected civilisations. Great-circle corridors, because the ley line hypothesis deserved a real test rather than a story. Documented Alignments, because what archaeoastronomers have actually measured belongs next to what is merely claimed. AI research reports, because the knowledge buried in academic papers deserved to be accessible to anyone willing to look. All of it, in one place, and all of it tested against chance.
Today Pyramason serves historians, archaeologists and enthusiasts across the world, with 188,772 verified ancient sites across 200+ countries and territories, a suite of professional research tools, and a growing community of people who share the same belief: that the honest questions about our past are still worth asking, and that the answer "consistent with chance" is an answer too.
