Santa Iglesia Catedral
The two buildings are joined and you enter from the north side into the New Cathedral, built 16th-18th century. Outside, note the fine Puerta de Ramos, mostly Renaissance but among its saints are an astronaut and an imp clutching an ice-cream cone. The interior is a baroque / Churrigeuresque creation, with fine ceilings, choir and main chapel. A door leads down into the Old Cathedral, 12th century and mostly Romanesque, with many frescoes.
The best of it is the grand exterior. Many visitors reckon it's not worth paying to see the ostentatious interior and endure the interminable audio guide.
