The Museum of Royal Barges (Museo de Falúas Reales) houses a collection of the ornate river vessels used by the Spanish royal family on the Tagus at Aranjuez from the 17th to the 19th centuries. The barges are extraordinary objects: elaborately gilded, painted, and decorated boats that were used for royal processions and entertainments on the river.
The museum is housed in a purpose-built boathouse in the Jardín del Príncipe, and the collection includes both large ceremonial barges and smaller pleasure boats. The scale of the craftsmanship is striking — these were floating throne rooms, and the surviving examples make it clear why contemporaries marvelled at the Aranjuez royal spectacles. Admission is included in most Aranjuez heritage tickets.
