Oviedo is the capital city of the Principality of Asturias in northern Spain and the administrative and commercial centre of the region. It is also the name of the municipality that contains the city. The city lends its name to the sudarium of Oviedo a religious relic revered there since the 9th century. t is said that two monks, Nolan and John, founded the city in 761. That settlement was soon to be completed with the construction of a small church dedicated to Saint Vincent. Nevertheless, the archaeological register has shown traces of occupation since the 1st century, in Roman times.
