Palacio-Castillo del Príncipe de Viana

Palacio-Castillo del Príncipe de Viana is a Gothic fortified residence in Sangüesa (also known by its Basque name, Zangoza), a small town in Navarre, Spain, that once served as a royal seat for the Kingdom of Navarre. The building dates back to the 13th century, with its present appearance shaped by a major remodel carried out in the second half of the 16th century.

Where does the palace's name come from?

The name honors the title "Prince of Viana," held by Charles, son of Queen Blanche of Navarre and John II of Aragon. During the wars between Castile and Aragon, Queen Blanche and her son set up their court in Sangüesa, turning this residence into one of the politically most significant buildings in the kingdom. That episode from the Navarrese dynasty's history is the reason the palace still carries the prince's name today.

What is the building's history?

The earliest record of a royal residence on this site dates to 1271, when King Henry I spent several days in Sangüesa. Shortly after, in 1280, the eastern tower was converted into a royal dwelling. In the early 14th century, the complex was expanded with a second, similar palace facing the town's main street, and the two buildings were joined by a gallery that enclosed the parade ground between them.

The palace hosted figures such as Charles II "the Bad" and the infante Don Luis during conflicts with Aragon, as well as Charles III "the Noble." In 1445, the General Courts of the Kingdom of Navarre convened in its halls — one of the most important legislative assemblies in the region's history.

After the conquest of Navarre in 1512, many of the kingdom's castles were demolished in 1516 on the orders of the regent, Cardinal Cisneros. The palace in Sangüesa survived because it was kept in use as a permanent military garrison, sparing it the fate of other Navarrese fortifications.

What does the architecture look like?

The building is Gothic in style, built from plain, well-cut ashlar masonry. What survives of the original complex is a two-story central block flanked by two square towers topped with crenellations and equipped with arrow loops. This layout — a solid residential block set between two defensive towers — is typical of Navarrese border residences that combined living quarters with fortification.

The palace was restored in 1960. It is now owned by the Government of Navarre and is used for tourism purposes.
