Sacsayhuamán Site-Emblem T-Shirt, Peru

The saw-tooth silhouette of Sacsayhuamán's zigzag terrace wall, the single most recognisable image of the site, printed alongside the geometry diagram Pyramason actually tested across Cusco's historic centre: a clean consistent-with-chance result, not an invented alignment. Beneath it: Sacsayhuamán, Peru, -13.507778, -71.982222. Those are Pyramason's own catalogued coordinates for a fortress built from blocks up to 200 tonnes, without iron or the wheel.

• Zigzag wall silhouette, the defining image of the site
• Geometry diagram shows Pyramason's real p=0.99 consistent-with-chance test result, with no invented mysticism
• Exact coordinates (-13.507778, -71.982222) printed beneath the monument and country
• Soft, pre-shrunk cotton in a minimalist gold-on-dark line-art treatment

Why this site. Sacsayhuamán carries more "impossible masonry" fringe baggage than almost any site in our atlas, and the real story (20,000 organised workers, period tools, verified by replication) is more impressive than the myth, not less.
