The Palace of the Dukes of Medinaceli was the residence of the Marquises of Priego after the destruction of the Castle in 1508 by order of King Ferdinand the Catholic, highlighting the figure of Catalina Fernández de Córdoba, a woman of great relevance in the history of Montilla, great patron of the arts.
The palace is a building of simple and sober aspect, which underwent an extension phase during the sixteenth century, was later restored and today, after being divided into two houses for private use. Its golden stone facade is articulated on a double floor with numerous openings in parallel positions and a main access on the right-hand side, which appears richly ornamented and whose upper balcony is flanked by the shields of the House of Priego and Feria.
To the left is the compass that connects the palace and the convent of Poor Clares, giving rise to the passage that leads to Benedict XIII Street. The facade, the only visible part, is very sober Mannerist style. The main portal located at one end of the facade and on the opposite side is the semicircular arch, known as the Santa Clara Arch, a passageway that communicated directly with the convent.
