San Vicente de Oviedo is a church and monastery in Oviedo, Spain. Its foundation in 761 is recorded in a charter known as the Pacto monástico de Oviedo ("Monastic Pact of Oviedo"). A copy made in the 12th century of the original that is dated 25 November 781 is considered the earliest document on the monarchy of the Kingdom of Asturias, although doubts exist as to the veracity of this document since the monastery, also called Antealtares in the Middle Ages, is not mentioned again until 969.
