What you’ll learn

  1. Begin with a vault that wants to spreadExplain why Gothic vaults create both downward load and sideways thrust, and trace a basic load path.Chartres starts with a roof that wants to spread; pointed arches and ribs organize its forces.
  2. Turn stone into a skeletonDescribe how clustered piers and flying buttresses distribute force through compression-based masonry.The cathedral concentrates structural work in a visible stone skeleton, especially outside the nave.
  3. Make the walls disappearConnect the structural skeleton to Chartres's tall clerestory, rose windows, and stained glass.Once force routes are concentrated, wall space can become openings filled with tracery, glass, and light.
  4. The cathedral is a balanced machineExplain why construction sequence, movement, monitoring, and repair are part of Gothic structural performance.A cathedral stays up through a long, maintained balance between geometry, mass, weather, and the ground.

Questions this course answers

Why does a masonry vault need more than support directly below it?

A vault carries downward load but also pushes outward, so its supports and buttresses must manage both components.

What is the main structural job of a flying buttress?

The flying buttress intercepts lateral thrust high on the wall and redirects it into a massive exterior support.

Why can Chartres have large clerestory windows?

Concentrated masonry routes allow the upper wall to be more open while the structure still carries compression and thrust.

Why is construction sequence part of the physics?

Temporary centering and staged supports keep incomplete masonry stable until the final load path is closed.
