Casa del Príncipe, Valladolid, Eclectic and Art Nouveau residential building on Acera de Recoletos, Valladolid, Spain.

Casa del Príncipe is an Art Nouveau residence in Valladolid distinguished by a cylindrical corner tower supported by cast iron pillars. The facade combines concrete and brick in a two-tone design adorned with plant motifs characteristic of the period.

Built in 1906 by architect Jerónimo Arroyo, the house marks Valladolid's modernization at the beginning of the twentieth century. Its construction demonstrates the adoption of new building techniques and modern materials like concrete that shaped the city's urban transformation.

The house reflects how wealthy families of the era designed their homes with elaborate facade details and ornamental ironwork that displayed their status and refined taste. This type of residence represented the modern, prosperous lifestyle emerging in Valladolid during the early twentieth century.

The building stands at the corner of Acera de Recoletos and Calle Colmenares, the street opened in 1893 on the grounds of former convents. The cylindrical corner tower and the brick facade are best seen from the opposite pavement of the Acera, where the whole elevation can be taken in at once.

The corner tower rests on slender cast-iron supports with an organic look, as if the metal were holding the cylinder up. The building was one of the locations of the film Un buen día lo tiene cualquiera, shot entirely in Valladolid in 2007.
