According to Isidore of Seville's Historia de regibus Gothorum, Vandalorum et Suevorum, the town of Oligicus was founded by Swinthila, Visigothic King of Hispania in order to control and punish the native Vascones people. However, this town was not heard of again until five centuries later, when the present-day town was founded and chartered. The Royal palace of Olite, a fine Gothic castle-palace, was the royal seat of Charles III of Navarre.
