Ramiro I (c. 790 – 1 February 850) was king of Asturias (modern-day Spain) from 842 until his death in 850. Son of King Bermudo I, he became king following a succession struggle after his predecessor, Alfonso II, died without children. During his turbulent reign, he fended off attacks from both Vikings and the forces of al-Andalus.[1] Architecturally, his recreational palace Santa María del Naranco and other buildings used the ramirense style that prefigured Romanesque architecture. He was a contemporary of Abd ar-Rahman II, Umayyad Emir of Córdoba.
