Palacio de los Marqueses de Peñaflor, Baroque mansion in Écija, Spain

The Palacio de los Marqueses de Peñaflor is a baroque noble mansion in Écija, in the Andalusian province of Seville, known for a long balcony that runs across the entire front facade. Inside, a central courtyard with white marble columns connects to rooms decorated with paintings and period furnishings.

Work on the palace began in 1700 under Antonio Fernández de Henestrosa, the fourth Marquis of Peñaflor, and took around 75 years to finish. Older structures already standing on the site from the 16th century were incorporated into the new building rather than demolished.

The palace is also called "palacio de los Balcones Largos" for the long balcony that follows the curve of the street, where the marquises appeared in public; its frescoes of landscapes with architectural frames and trompe-l'oeil are by the Madrid painter Antonio Fernández. The building now serves as the seat of the Fundación de los Marqueses de Peñaflor, and has housed the municipal library, a music conservatory and the city's notarial archive.

The palace sits in the center of Écija and is easy to reach on foot from most of the town's other sights. It is worth checking opening hours before you visit, as access to some parts of the building may not always be available.

The long balcony that follows the curve of the street is decorated with polychrome frescoes by the Madrid painter Antonio Fernández, showing landscapes with architectural frames and trompe-l'oeil effects. Visitors often walk beneath it without looking up at the painted scenes.
