Hidden history

Found, Not Built

A white domed basilica on Montmartre, standing on deep piers sunk into a hill riddled with old gypsum quarries.

  1. Why researchers flag it

    Its piers go down through a hill full of old gypsum quarries.

  2. Piers into the hill

    Its foundations go down through quarried ground on deep piers.

  3. Self-cleaning stone

    The travertine whitens with rain.

  4. Architect of record

    Paul Abadie (born 1812) was about 62 when credited with the design in 1874. The Architects of Record page asks how often a young or little-known name delivers a landmark.
