The History of Charlemagne and Roland recounts how the emperor and his Frankish army, returning after their victorious campaign to liberate Spain and the shrine of Compostela, were challenged by Furra, king of Navarre at a place called Monjardin.
The pilgrimage road between Estella and Najera near Los Arcos passes between the Sierra Montejurra to the south and the steep eminence of mount Monjardin immediately to the north. Monjardin dominates the road and the countryside for miles around. At its crown is the old castle of San Esteban de Deio which played a vital role in the Reconquest of Navarre in the very early tenth century.
Captured from the Saracens by Sancho Garcia Ist in 908, the Navarrese Christians were then able to use it as a base to control the valley of the Rio Ega and then advance south of the Ebro. When the Moors returned in force under Abderrahman III and razed Pamlona in 924, only the defensive position of Monjardin was able to resist.
The survival of Monjardin was attributed to a legendary cross which miraculously appeared during battle. The cross came to be venerated by the local populace who covered it in silver and can be seen to this day in the church of Villamayor de Monjardin.
When Charlemagne accepted the king of Navarre’s challenge at Monjardin, he prayed on the eve of battle to know which of his men were to be slain the next day. “Charlemagne therefore prepared for battle, but desiring to know who should perish in it, he entreated the Lord to show him”. In the morning these were miraculously designated by ”a red cross which appeared on their shoulders behind”.
The emperor ordered that these men should be confined to a chapel and the fight should take place without them. Furra and three thousand of his army were killed, “these were all Saracens of Navarre”. Although victorious, Charlemagne was dismayed to find on his return to the chapel that all those held inside were now dead, their status as martyrs was not to be denied. “Christian warriors” declared the emperor, ”though the sword slew you not, yet did you not lose the palm of victory or the prize of martyrdom”.
The castle of San Esteban de Deio was renamed Monte Gargiani in memory of Sancho Garcia Ist, who was buried in the chapel of the castle. When in 1090 the town of Estella was founded by Sancho Ramirez king of Aragon and the French bishop of Pamplona, Pierre d’Andouque, Monjardin’s defensive role was revived, this time as a bastion between the competing interests of Aragon and Navarre and the strategic role of the pilgrimage road. Monte Gargiani was renamed Monjardin.
