Abstract
The presence of a wide group of full-size architectural tracings engraved on the walls of the lower cloister of the monastery of San Millan de la Cogolla, Yuso, made it necessary to develop and to apply a methodology to record, preserve and openly disseminate the information provided by their walls. The documentation process started with the copy of the engravings in plastic sheets, which were later on digitized and superimposed on the three-dimensional photogrammetric model. The preservation and dissemination by means of a digital format is based on the storage by an institutional repository connected to Europeana. The plastic sheets with the copies have been saved at the archive of the monastery. Likewise, an Augmented Reality application for visualizing the drawings on the walls of the cloister has been created.
