physical description of the monument

architecture

The building has two levels; the main nave sustained by columns crowned by cross vault and flat ceiling, with elevated large windows at sides closed by stained glass windows; and a second level, in a lower height, corresponding to the aisles and their chapels, with common cross vaults and a second row of large stained glass windows.

Outside, both levels are sustained and united by buttresses and flying buttresses joined by the tower of a winding staircase near the apse. The heptagonal apse contains seven radiating chapels and a monumental portal on each side, after which section there are five sections of radiating chapels.
