Fuerte Gazteluzarra, located near Castejón and the Belate Pass in Navarre, represents a strategic 19th-century fortification constructed following the Third Carlist War. Approved by King Alfonso XII in 1879 and completed in 1883, the fort was built to control this mandatory passage connecting the Pamplona Basin with the Baztán valley, preventing potential future royalist uprisings. The name derives from Basque, meaning 'old castle,' reflecting the region's linguistic heritage. Positioned at an elevated strategic vantage point offering panoramic views spanning tens of kilometers, the ruins stand within walking distance of the Belate Pass and have been gradually restored through efforts by local communities and Camino de Santiago pilgrims dedicated to preserving this piece of regional military history.
