Canena Castle is a Renaissance building from the 16th century, designed by the Spanish Renaissance architect Andrés de Vandelvira (1509-c. 1575). It belonged to Francisco de los Cobos, private secretary to Charles I and a great patron of the Renaissance in Úbeda and the surrounding area.
The building we see today dates from the 17th century. It adopts an almost square ground plan delimited by two large towers at the ends of the main façade and two smaller and apparently incomplete towers on the rear façade, all them circular. One of the most imposing features is the square keep, which used to be surrounded by a moat, now filled in, and accessed by a drawbridge.

The oldest parts of the present red-brick church are from the 1300s. In the late 1400s the church was enlarged to the appearance it has today. The church has been modified both internally and externally several times, among other things after the fires in 1699 and 1889. There are lot of well-preserved mural paintings in the walls.
