Questions, answered.

Pyramason is a research platform for ancient mysteries. It combines an interactive 3D map of 188,772 ancient sites across 200+ countries and territories with geometry engines that test every pattern against chance, great-circle corridor analysis, documented archaeoastronomy with sources, AI-powered research reports, sky and shadow tools, a frequency lab and community collaboration. Think of it as a professional research toolkit for anyone fascinated by the ancient world, built to tell you honestly when a pattern is real and when it is not.

Yes, the core map is completely free: all 188,772 sites with full search and filters, 3D Terrain View, Antiquity and Empires, Discovery Mode, Documented Alignments with the Azimuth Identifier, Gnomon Shadow, the Frequency Centre with the Frequency Lab, Antipode Calculator, Draw & Measure tools, standard snapshots and data export up to 25 sites at a time (100 a day). Pro features unlock AI tools, sacred geometry, great-circle corridors, the Mystery Decoder, community features and more.

No, you can explore the full map without an account. Creating a free account lets you save favourites, access community features and manage your subscription if you upgrade to Pro.

Antiquity is a mode, not a filter. It strips the modern world off the map, every road, motorway, airport, present-day city label and national border, repaints the earth as aged parchment and the seas as ink, and raises 58 great cities of the ancient world under the names their own people used: Waset, Ilion, Qusqu, Chang'an, Meroë, Mohenjo-daro. Empires draws 16 civilisations at their greatest extent, each marked by an engraved seal at its capital. Hover a seal to light that empire's borders, click it for a card giving its apex year, ruler and reach. Both are free, both work over any base map, and they are designed to be read together. Neither invents ancient coastlines or borders we cannot source.

Yes. Pyramason publishes a free MCP endpoint at map.pyramason.com/mcp. Paste that address into Claude, ChatGPT or any MCP-capable assistant and it can search the atlas, pull a single site's full record, and run the golden-ratio alignment and great-circle corridor engines directly, each returning a null model with a p-value. No key is needed: free keyless access allows 300 tool calls a day. Pro subscribers can generate a personal API key with 20,000 calls a day from the map's Settings.

Pyramason runs in any modern browser: Chrome, Firefox, Safari, Edge. It works on desktop, tablet and mobile, though we recommend desktop or laptop for the best research experience, particularly for sacred geometry and corridor analysis.

Our database is built entirely from open-licensed sources: Wikidata (CC0 Public Domain, about 166,000 sites), the Pleiades Gazetteer (CC-BY 3.0, about 22,400 sites, specialising in ancient world geography) and a small set of hand-verified curated additions, giving 188,772 in total. All data is legally sourced, fully documented with provenance records, and free of proprietary restrictions.

Sixteen categories: Settlements (50,648), Temples (40,555), Burial Mounds (30,542), Fortifications (18,101), Rock Art (10,090), Monasteries (9,616), Cathedrals (6,147), Dolmens (5,738), Roman Sites (5,505), UNESCO World Heritage (5,086), Standing Stones (2,367), Stone Circles (1,613), Crosses & Runestones (1,305), Sacred Sites (789), Passage Tombs (435) and Pyramids & Ziggurats (235).

All sites are sourced from established open databases and include coordinates, names, country and, where available, region data. Coordinates are verified at source. Archaeological databases are always evolving; if you spot an error, contact us at contact@pyramason.com.

Yes. As open-licensed sources are updated and expanded, we update our database accordingly. Pro users can already submit new sites with supporting sources through the map.

Paste map.pyramason.com/mcp into any AI that speaks MCP: Claude, ChatGPT, Cursor and more. Your AI can then search the 188,772 sites, run the golden ratio engine, fit great-circle corridors with p-values and pull real coordinates. It works free for everyone at 300 calls a day; Pro researchers get a personal key with 20,000 calls a day, generated in the map's settings.

Browser-based AI agents (like Claude in Chrome) can drive the map's visual Pro features through your own logged-in session, exactly as you would. The MCP connection itself is data only: search, measure, analyse.

Pro (£12.99 a month) unlocks the full research toolkit: Sacred Geometry Analysis scored against a chance baseline, Great-Circle Corridors (the ley line hypothesis) with p-values and AI context, Platonic Solids checked against random rotations, Natal Charts illustrated with original 1824 star atlas engravings, Site Connections, AI Research Reports, the Mystery Decoder with its evidence grade A, B, C or none, Map Style Switcher, Travel Areas and Directions, hi-res Snapshots, Astral Projection flight with video recording, the Cinematic Director with ten hands-free shot templates recording up to 4K, the full Community suite with five researcher channels, site submission, data export up to 1,000 sites at a time (5,000 a day), a personal MCP key with 20,000 calls a day and priority support.

It detects mathematical proportions and geometric patterns between selected ancient sites, including phi (the golden ratio), Fibonacci chains, Pythagorean triangles and other ratios. Select multiple sites and run the analysis. Every hit is compared with an empirical chance baseline, so you see how many such ratios a random set of sites would produce; AI interpretation explains what the detected patterns may mean in historical and cultural context, and stays inside what the numbers support.

Ley lines are the hypothesis that ancient sites were placed on straight lines. Pyramason tests it. Auto-detect scans up to 500 visible sites and finds collinear groups within an adjustable tolerance, or you can draw corridors manually. The map calculates the true great-circle fit, the km tolerance, end-to-end distance and which sites fall along the path, then shows the p-value against a null model and a caveat when the null is too tight to trust. Pro users also get AI context on the historical, astronomical and cultural background of the sites on the line.

Some are, most are not, and the map tells you which. Every geometry engine (Sacred Geometry, Great-Circle Corridors, Platonic Solids, the Mystery Decoder) tests its hits against chance using real-site null draws or random rotations, and reports the result. When we ran the ten most famous regions in the world through the engines, none scored above chance once each place is counted once. The documented archaeoastronomy is a different matter: Newgrange's roof-box, the Giza cardinal alignment (3.6 arcminutes), Karnak's winter solstice axis, the Teotihuacan grid, Stonehenge's axis, Angkor Wat's equinox and El Caracol's Venus sightlines are published measurements. They are listed in the free Documented Alignments tool with author, year, publication and link, each tagged documented, contested, claimed or rejected, and recomputed by the map for the site latitude and building epoch.

A Pro tool that measures first and speaks second. For any site it runs the regional and worldwide famous sets through the alignment engine with 2000 real-site null draws, fits three great-circle corridors with a rotation null, checks solstice, equinox and lunar standstill bearings to every neighbour within 30 km at the chosen epoch against the chance coverage, and reads the catalogue density. The output is an evidence grade A, B, C or none, followed by a 120-word brief that may only quote the numbers. It says "On record in the literature" for sites in Documented Alignments, and it has an epoch selector with recompute.

A free tool that draws the shadow-tip track of a vertical rod for any place, date and epoch on the map at true scale, with sunrise and sunset azimuths, noon altitude and shadow length. The equinox buttons reproduce the method (Dash 2017) that gave the Great Pyramid true north to within a few arcminutes.

Solfeggio, Schumann, binaural and custom tones (432, 440, 256, 136.1, 110, 111, 300, 528 and 7.83 Hz) with volume and a sleep timer, plus the Frequency Lab. The Chambers tab lists documented archaeoacoustics with sources: Jahn, Devereux and Ibison (1996) measured 95 to 112 Hz resonances in six British and Irish chambers, the Hal Saflieni Hypogeum at 70 and 114 Hz, the Chavin de Huantar pututus at about 300 Hz, Stonehenge's 0.64 s reverberation from the Salford scale model and the Chichen Itza staircase chirp, with a room mode calculator. The Tunings tab plays Pythagorean, just intonation, seven Babylonian modes and Greek tetrachords. The Tools tab has a sine sweep and a microphone spectrum analyser (FFT 8192) for measuring real rooms. The Cymatics Lab simulates a real free-edge circular plate (Kirchhoff-Love theory, Leissa 1969) in five materials. We make no health or healing claims about any tone; the tones are there to be heard and measured.

Yes. The Pyramason MCP server exposes six tools: search_sites, sites_near, get_site, golden_alignments, ley_line and site_stats. The geometry tools return null models with p-values. It is keyless for up to 300 calls a day; API keys for higher limits are available at pyramason.com.

Click any site on the map, open its info panel and click AI Research. Pyramason sends the site's details to Claude AI, which generates a research report covering the site's history, archaeological significance, competing theories, known measurements and cultural context. Reports run 1,500 words and up, averaging around 1,950, and each one is cached once generated so it loads instantly for every researcher afterwards.

Yes. Sky Align and the Natal Charts run on real planetary ephemeris: NASA-grade approximate positions valid from 3000 BCE to 3000 CE, with epoch-aware obliquity, solstice azimuths computed from latitude, a Sun standard altitude of -0.833 degrees and proper ascendant calculations. Polar cases are explained rather than dropped. Sky Events flags each event as documented (published measurement), claimed (asserted, contested) or atmospheric. You can reconstruct the sky over Stonehenge on a solstice five thousand years ago, and the results are mathematics a researcher can cite.

An immersive first-person flight mode. Fly freely across the ancient world, create custom waypoint paths for cinematic flythroughs, and record video footage. A cinema mode hides the whole interface for clean recordings. The Cinematic Director lives in the gold bar at the top of the panel. Exclusive to Pro subscribers.

The map films itself. Select your sites, pick one of ten shot templates (Close Orbit, Orbit, Descend, Reveal, Approach, Skyfall, Drift, Sweep, Globe and Pilgrimage) and press ACTION. The Director hides the whole interface, flies the scenario hands-free, records it and downloads the finished clip, up to 4K. A double-pass system flies each shot once to load every tile, then records a second, identical pass, noticeably smoother, especially on older machines. Built for content creators: a finished site film with no editing software. Find it under DIRECTOR in the map's top bar, or inside Astral Projection. Exclusive to Pro subscribers.

Mapbox GL JS for the 3D map, Supabase for the database and authentication, Claude AI (Anthropic) for all AI research features, Turf.js for geodesic calculations, and an open MCP server so any AI can connect to the data.
