The church's only chapel serves as a tabernacle. This room contains a large painting of Calvary. There are also a large number of notable paintings by names such as Echave Orio, Simón Pereyns, Sánchez Salmerón Caravaggio, Francisco Martínez, Luis Arciniegas and Juan Martínez Monteñés. The baptismal fonts are decorated in acanthus leaves, among which is a pre-Hispanic style skull. The organ is Baroque from the 17th century. The pews are made of red cedar as are the two pulpits, all made by Juan Rojas in the 18th century.
