Photographer and architect Yiorgis Yerolymbos spent a decade documenting with his camera Renzo Piano's Stavros Niarchos Foundation Cultural Center in Athens, Greece. Of all the images that have been captured, one grouping stands out: the ground-plan photographs of the construction of the Cultural Center, images that were created during aerial orbits from the site’s tower cranes. These photographs are records of an ever-changing environment, they document and interpret the evolving phases of the construction site, following the vocabulary of architecture, yet recorded in the language of. Borrowing their name "Orthographs" from Leon Battista Alberti's description of the ground plan during Renaissance, this body of work attempts to record the ephemeral intermediate stages of the construction of architecture and the human effort behind it before they slowly fade from memory.
