The first Vannes Cathedral was erected around 1020 in Romanesque style. The tower is only structure left from it and accommodates the four bells of the church. The present Gothic building was erected on the site of the former cathedral. Its construction extends from the 15th to the 19th centuries, or if the length of the existence of the 13th century Romanesque bell tower is included, a total of seven centuries of construction. In this period the nave and the ornate gateway at the northern end of the north transept – whose twelve niches, according to Breton custom, were supposed to accommodate the Apostles – were built high. The northern tower is the main remnant of the former Romanesque building, while the vaults and the choir were built between 1771 and 1774.
The façade was carved in 1857 in a neo-Gothic style. Outside, in front of the central pillar of the large gate, stands a statue of the Dominican monk St. Vincent Ferrer, from Valencia. His activities in the 15th century greatly influenced Christianity in Vannes. The northern façade opens onto the garden of the cloister (ruins from the 16th century) and the Rue des chanoines ('Street of the Canons') through the beautiful portal at the top of the north transept, built in a Flamboyant late Gothic style (1514), and decorated with twelve niches designed to house statues of the twelve apostles. The cross, visible close to the northern façade, dates back to the 15th century and was brought from the cemetery.
During the Middle Ages, the floor of the cathedral had been covered by tombstones. For hygienic reasons, only the tradition of burying the bishops in their episcopal church has been preserved. However, some tombstones have been returned and can be seen today. The cathedral has only retained tombs dating back to the 17th century. Two bishops' tombs can be found in the crypt under the choir.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.
