The Palace of Albéniz, formerly known as the Royal Pavilion of Montjuic, is a palace located on the Montjuïc mountain, in Barcelona, Spain, that currently serves as the official residence of the Spanish royal family in the region.
Since its construction it has been adapted to its different functions: first, as a place of representation of the Crown during the 1929 Barcelona International Exposition and, after it, as accommodation for illustrious personalities. It has currently become the official residence of the Spanish royal family during their official stays in Catalonia.
