Palacio de la Alfranca, Aristocratic palace in Pastriz, Spain

Palacio de la Alfranca is a late-18th-century neoclassical palace with a rectangular plan and three floors, its main facade marked by a projecting square portico with Ionic columns at the angles. The portico supports a first-floor balcony, and six windows flank the entrance on the ground floor. A wide garden with a tree-lined walk leads to the portico.

The palace was built in the 18th century and later served as a residence for General Palafox during the Spanish War of Independence, when Zaragoza's citizens sought his leadership against Napoleon. The site thus became connected to major military and political events of that era.

The palace now serves as an International Center for Water and Environment, where research and learning programs focus on water management and ecological issues affecting the region. This purpose gives the building a living role beyond its past as a private residence.

The palace sits about 10 kilometers from Zaragoza city and is located within the Galacho de Alfranca Natural Reserve, near a former monastery and the town of Burgo de Ebro. Its position makes it accessible yet surrounded by protected natural areas.

The palace's alternative name, Casa Palafox, recalls General José de Palafox, who was staying here when Zaragoza's residents came to ask him to lead the city's defence at the start of the Spanish War of Independence. The stables form a separate 18th-century building of two floors beside the three-storey palace.
