Palacio del Marqués de Portugalete

The Palacio del Marqués de Portugalete was a grand palace built in the 1860s, located at 56 Calle de Alcalá, on the corner of Calle Alfonso XI, in Madrid. Also known as the Palace of Bailén, it belonged to the family of Francisco Javier Castaños y Aragorri, a descendant of General Francisco Castaños, who was the victor at the Battle of Bailén. It was built by architect Adolfo Ombretch, who also built the nearby palace of Linares. For many years it was a venue for the wealthy elite to meet and discuss national politics. It was demolished after the Spanish Civil War, and in 1946, replaced by the National Institute of Forecast, now occupied by the National Institute of Health.
