Virtual image of the reconstruction of the transcendental of Master Mateo. The plan of the monument has a central nave that leads to the door of the choir, flanked by two other naves on each side, where the funerary chapels would be found. Each nave would consist of two sections, separating the space with four pillars or columns and covered by groin or ribbed vaults. On these the platform pavement would settle. The tribune or leedoiro was the space at the top from which the epistle and gospel were read, and was also used as a venue for chapter meetings. The grandstand had two lateral facades and a main one, which stands out in this image.
