The Old Cathedral (Alter Dom) in Linz was built by Jesuits between 1669 and 1683 in Baroque style. From 1785 to 1909 it served as cathedral of the Diocese of Linz.
The church was erected near the former Jesuits' College at the south end of the Hauptplatz. The church was originally called the Church of Ignatius and was dedicated to Saint Ignatius of Loyola, who founded the Jesuit Order.
The Jesuit Order was dissolved in 1773 by Pope Clement XIII. The Diocese of Linz and St. Pölten von Passau was effectively founded in 1783 by a decree of the Emperor Joseph II (1741–90) without advance approval from Rome. The emperor appointed the bishop and designated the former Jesuit church as the cathedral. The diocese was officially established by a papal certificate of 28 January 1785. Bishop Gregorius Thomas Ziegler (1827–52) led an era during which the church was restored. In 1909 the function of cathedral was transferred from the Ignatius church to the new building. The Jesuits returned in 1909.
The exterior of the church is relatively plain, with two towers on either side of the main door, topped with onion domes. The interior is decorated in lavish Baroque style, with pink marble columns. There are three side chapels on either side of a wide main nave.
The church has an elaborately detailed wooden pulpit, and a high altar made by Giovanni Battista Barbarino and Giovanni Battista Colombo that incorporates many statues in marble. Antonio Bellucci (1654–1726) made the painting of Saint Aloysius that is located above the altar. The stalls in the presbytery were carved by local artists, and are decorated with the faces of monsters and dwarfs. The carved choir stalls from the 17th century were transferred from Garsten Abbey. The Baroque organ was built by Franz Xaver Krismann, with alterations requested by Bruckner. The organ has not been modified.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.
