the gothic influence can be clearly seen in the nave with its decorative arches and vaulted ceiling. repairs and additions have also led to decorations in the renaissance and baroque styles in the chapels. the cathedral's main altarpiece in the flamboyant gothic style is believed to be the work of cornielles de holanda with five vertical panels each divided into horizontal compartments. martin of tours is depicted in the central panel as the cathedral's patron saint while scenes from the life of jesus and mary can be seen in the other panels. on either side of the main altar, there are two other altars representing the martyred saints of ourense: facundus, primitivus and euphemia.
