Nuestra Señora de la Asunción (also known as Catedral de la Campina, Spanish for "Cathedral of the Countryside") is a Roman Catholic church in Bujalance, Andalusia, southern Spain.
The Renaissance high altar (16th century) is attributed to Guillermo de Orta and Andrés de Castillejo, with paintings by Leonardo Enríquez de Navarra. Next to the altar is a small hexagonal chapel in Baroque style, from the early 18th century. Other artworks include the Roccoco case by the Cordoban goldsmith Damián de Castro, a large canvas of the Battle of Lepanto and a side Baroque portal in pink marble.
The tilting tower, begun in 1611 and finished in 1788, has a height of 55 meters.
