The cathedral stands tall, crafted in granite ashlar, its roofs adorned with slabs of the same material. A Romanesque masterpiece, it follows a Latin cross plan, featuring a longitudinal arm and a transept with three naves. An ambulatory graces the apse, and a gallery runs the entire perimeter. Neatly arranged side chapels add to the temple's charm, each with its unique space and character. From the Romanesque era, only a few chapels of the ambulatory have been preserved.
