This project investigates the evolving role of the architectural section through the lens of Mario Botta’s Church of San Giovanni Battista in Mogno. The study situates the section within a historical continuum, from its origins in pre-perspectival practices to its reinvention through modern technologies such as X-ray imaging and beyond into the speculative possibilities of micro- and nano-scale visualization.

The church, with its precise geometry and material articulation, offers an ideal case for examining how sections reveal both structural clarity and spatial experience. By re-drawing the church in the representational styles of different eras, the project reenacts the evolution of the section: from early orthographic projections and unrolled surfaces, to axonometric constructions, to technologically mediated modes of “seeing through” such as radiography. Each method uncovers new layers of meaning and highlights the section’s ability to mediate between interior and exterior, light and mass, surface and depth.
