The cathedral was built from 1572 to 1600, when the bell-tower was complete. Among the architects were Martín de Castañeda, Quinto Pierres Vedel, and Alonso del Barrio de Ajo. The church has a single nave and the ceiling has Gothic tracery. The nave interior and the Chapel of the Virgen del Pilar was redecorated in stucco and gilding in Baroque style.
