The first written text about an abbey dates from the 9th century. When Christianity expanded to this area, around the 4th century, Mont Tombe, the original name of Mont Saint Michel, was part of diocèse d’Avranches. By the middle of the 6th century, christianism had a stronger presence in the bay. By this time, Mont Tombe was populated by religious devots, hermits (probably some Celtic monks) resupplied by the curé of Astériac, that took care of the site and led a contemplative life around some oratories.
In 710, Mont-Tombe is renamed Mont-Saint-Michel-au-péril-de-la-Mer (Mont Saint Michel at the peril of the sea) after erecting an oratory to Saint Michel by bishop Saint Aubert of Avranches in 708. According to the legend, Aubert received, during his sleep, three times the order from Saint-Michel to erect an oratory on the Mont-Tombe. The archangel left his finger mark on Aubert's skull. This skull is displayed at the Saint-Gervais d'Avranches basilica was such a scar on it.
This sanctuary should be, according to the archangel, a replica of the Gargano in Italy (from the 5th century). Aubert had a local religious artifact removed and instead a circular sanctuary built, made of dry stones. Around 708, On October 16 709, the bishop dedicated the church and put twelve chanoine there. The Mont-Saint-Michel was born. The remains of the oratory were found in the chapel Notre-Dame-Sous-Terre. This sanctuary contained the tomb of Aubert and most likely the artifacts brought from Gargano. The chapel Notre-Dame-Sous-Terre is today under the nave of the abbey-church.
The first buildings became too small and under the Western Roman Empire multiple buildings were added. In the 10th century the Benedictine monks settled in the abbey, constructing the Romanesque abbey church with its high vaulted ceilings and moulded arches, monastery and crypts at the apex of the rock.
Through successive centuries of the Middle Ages and with increasing numbers of monks and pilgrims both the abbey and village were extended until in the 13th century they stretched down to the foot of the rock.
By the 14th century and the Hundred Years war, the abbey had to be protected behind a massive set of military ramparts, enabling it to successfully hold out successfully through many English sieges lasting over 30 years and in doing so the Mount became a symbol of French national identity.
In 1421 the original Romanesque chancel (choir) of the abbey church collapsed and was replaced in the 15th century by a flamboyant Gothic structure, marking completion of the last major construction works at the mount. The abbey today is thus an exceptional example of the full range of medieval architecture.
Over the 16th and 17th centuries religious ideals waned and the number of monks dwindled until by 1790 the monastery was disbanded and the monks left the mount. This paved the way for the fortress to be turned into a prison in 1793, a situation which lasted through the days of the French Revolution and Empire until imperial decree in 1863 finally overturned the sacrilege.
In 1874 Mont Saint-Michel was designated as a French historical monument and major works have continued now for over a century to restore the mount to its former splendour, improving both the abbey interior and exterior. With the celebration of the monastery's 1000th anniversary in the year 1966, a religious community returned to the mount, perpetuating spiritual prayer and welcoming the mount's original vocation.
UNESCO recognised the unique character and historical importance of Mont Saint-Michel by classifying it as a world heritage site in 1979.References:
The Mosque–Cathedral of Córdoba, also known as the Great Mosque of Córdoba and the Mezquita is regarded as one of the most accomplished monuments of Moorish architecture.
According to a traditional account, a small Visigoth church, the Catholic Basilica of Saint Vincent of Lérins, originally stood on the site. In 784 Abd al-Rahman I ordered construction of the Great Mosque, which was considerably expanded by later Muslim rulers. The mosque underwent numerous subsequent changes: Abd al-Rahman II ordered a new minaret, while in 961 Al-Hakam II enlarged the building and enriched the Mihrab. The last of such reforms was carried out by Almanzor in 987. It was connected to the Caliph"s palace by a raised walkway, mosques within the palaces being the tradition for previous Islamic rulers – as well as Christian Kings who built their palaces adjacent to churches. The Mezquita reached its current dimensions in 987 with the completion of the outer naves and courtyard.
In 1236, Córdoba was conquered by King Ferdinand III of Castile, and the centre of the mosque was converted into a Catholic cathedral. Alfonso X oversaw the construction of the Villaviciosa Chapel and the Royal Chapel within the mosque. The kings who followed added further Christian features, such as King Henry II rebuilding the chapel in the 14th century. The minaret of the mosque was also converted to the bell tower of the cathedral. It was adorned with Santiago de Compostela"s captured cathedral bells. Following a windstorm in 1589, the former minaret was further reinforced by encasing it within a new structure.
The most significant alteration was the building of a Renaissance cathedral nave in the middle of the expansive structure. The insertion was constructed by permission of Charles V, king of Castile and Aragon. Artisans and architects continued to add to the existing structure until the late 18th century.
The building"s floor plan is seen to be parallel to some of the earliest mosques built from the very beginning of Islam. It had a rectangular prayer hall with aisles arranged perpendicular to the qibla, the direction towards which Muslims pray. The prayer hall was large and flat, with timber ceilings held up by arches of horseshoe-like appearance.
In planning the mosque, the architects incorporated a number of Roman columns with choice capitals. Some of the columns were already in the Gothic structure; others were sent from various regions of Iberia as presents from the governors of provinces. Ivory, jasper, porphyry, gold, silver, copper, and brass were used in the decorations. Marvellous mosaics and azulejos were designed. Later, the immense temple embodied all the styles of Morisco architecture into one composition.
The building is most notable for its arcaded hypostyle hall, with 856 columns of jasper, onyx, marble, granite and porphyry. These were made from pieces of the Roman temple that had occupied the site previously, as well as other Roman buildings, such as the Mérida amphitheatre. The double arches were an innovation, permitting higher ceilings than would otherwise be possible with relatively low columns. The double arches consist of a lower horseshoe arch and an upper semi-circular arch.
