Vicente Luis Rosell Roig spent 6 years developing a model published in NPJ Heritage Science proposing helical pathways on the pyramid's edges using specific stone courses, with ramps on all four faces. The block-by-block simulation suggests the Great Pyramid could have been completed in under 27 years.
New paper proposes Integrated Edge-Ramp System for Great Pyramid construction

Key facts
- Vicente Luis Rosell Roig published a new paper in NPJ Heritage Science journal proposing an Integrated Edge-Ramp System
- The model uses helical pathways on the edges of the pyramid formed by emitting specific courses of stone on the perimeter
- Multiple ramp systems started on each of the four faces of the pyramid, unlike Jean-Pierre Houdin's single internal spiral ramp
- Rosell Roig worked on the idea for six years, moving from hand sketches in 2020 to full 3D models simulating construction block by block
- The model suggests the Great Pyramid could be built in under 27 years
- Evidence for four perpendicular ramps exists on the smaller Sinki Pyramid, one on each face
