A cavern of blue-grey metal opens inside an old stone building. Broad columns curve upward and join overhead, their surfaces broken into hundreds of triangular planes. Small round rivets follow the seams, turning each bend into a visible piece of construction. The closest panels are dark and mottled, while those beside the tall window brighten to pale silver.

A smooth stone path winds between the rising forms and continues through an opening at the back. Beyond it, a plain wooden bench rests against the original masonry, providing a familiar measure of the new structure’s scale. The old wall remains visible at the entrance, where a small warm lamp lights rough stone beside the cool metal. Scratches and slight changes in panel angle keep the surface from becoming uniform. Daylight skims some facets and leaves others in deep shadow, making the vault feel carved by light even though every part is assembled. The passage offers a clear view from entrance to far wall beneath its continuous angular ceiling.
