[02] Narrative

One slot of light

The chapel occupies the last cut face of a quarry closed in 1971. Its walls are cast from aggregate crushed on site, so the building is literally made of the mountain it replaces.

A single 90-millimetre slot in the roof is the only opening. At noon on the summer solstice, the beam lands exactly on the altar stone.
