Church turned Concathedral
The Santa María Concathedral presides over the Plaza of Santa María and the most important religious monument in the city. It was built in the Gothic style between the 15th and 16th centuries on the remains of a previous Romanesque structure from the 13th century. It was declared a Historic-Artistic Monument. The doorways are Gothic although some have Romanesque touches.
The most notable aspect of the exterior is the high 3-chamber bell-tower visible from around the city and which you can visit via an interior stairwell (which I’d recommend since the views are incredible). In the Plaza of Santa María, there’s a bronze statue of San Pedro de Alcántara by the sculptor Pérez Comendador.
