San Vicente de Oviedo is a church and monastery in Oviedo. 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 and 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. According to the charter of 781, twenty years before, in 761, the monks Máximo, with his serfs, and Fromestano, founded a church in locum quod dicunt Oveto (the place called Oveto), which was to become the city of Oviedo.
Transformed into a monastery, the first abbot was Oveco, documented between 969 and 978, and the first reference mentioning that it followed the Benedictine Rule is dated in 1042.
The style of the building is Romanesque, although reworked in the 11th and 12th centuries. Its cloister is an official National Historic and Artistic Monument and since 1952 houses the Archaeological Museum of Asturias.
The Archaeological Museum of Asturias hosts collections of the Asturian Neolithic, Megalithic, Bronze Age, Iron Age, Astur hill fort culture, Roman period, and of the Gothic, Pre-Romanesque and Romanesque periods of the Kingdom of Asturias. The museum also includes sections of Asturian Ethnography, Heraldry, Medieval and Modern Epigraphy, Spanish Numismatics, a European Medal Section, and Armor.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
