Palace of Infante don Luis, 18th-century palace in Boadilla del Monte, Spain.

The Palace of Infante Don Luis is a three-story structure built with red brick and granite details, displaying multiple ornamental pediments across its rectangular form. The complex includes decorated interior spaces, a restored chapel, surrounding gardens, and various outbuildings that complete the estate.

Construction took place between 1763 and 1765 under the direction of Infante Luis of Spain, who was the brother of King Charles III. The building incorporated an earlier structure on the site and transformed it into a major residential complex.

Luigi Boccherini stayed at the palace under the protection of Infante Luis during his years in Spain; the sources record his presence among the household but name no work composed there. The Infante's own chapel, with Corinthian motifs, marble, bronze and stucco, holds the pantheons of his daughters María Teresa de Borbón y Vallabriga, Countess of Chinchón, and María Luisa de Borbón y Vallabriga.

The palace stands in the town centre of Boadilla del Monte, west of Madrid, with its entrance façade facing northwest and the garden façade facing southeast. The grounds are laid out in terraces reached by stairways, with an upper and a lower garden separated by two galleries. The building has been closed to the public for much of its recent history, so access should not be assumed.

During the Spanish Civil War, the building sustained heavy damage and lost numerous art collections before being declared a National Monument in 1974. This difficult period left its mark on the structure and accounts for the careful restoration work visible throughout the rooms today.
