The corn-yellow facade of this cathedral dominates the central plaza. Inside you'll find beautiful interiors of ocher, blue, green, and gold with angels and cherubs smiling from the ornate ceiling corners. It holds a pantheon of Salta's luminaries, including local freedom fighter and strongman Martín Miguel de Güemes. There is a lovely side gallery of arches and beautiful floor tiles and an elaborate pulpit is perched to one side like a tiny gilded balcony.
