Herrenalb Abbey is a former Cistercian monastery founded probably in 1147 or 1148 by Count Berthold of Eberstein. The new monastery was settled by monks from Neubourg Abbey in Alsace.
The abbey owned scattered estates and communities in the Alb valley in the northern Black Forest. The abbey was however never able to concentrate its lands so as to maximise their economic potential, and never became particularly wealthy. The abbey at some stage received a privilege as an Imperial abbey, but appears to have lost this status in 1497, with the abbey's territory being secularised to Württemberg, with Baden gaining some of the outlying villages.
It was laid waste in the German Peasants' War of 1525. After Duke Ulrich introduced the Reformation to Württemberg in 1534, the monks were forced to leave the abbey in 1536. A school was set up in the buildings in 1556 but was closed again in 1595.
Some buildings still remain of the original monastic complex, among them what appear to be the abbot's lodgings and the infirmary, besides ruins of the cloisters. The Romanesque tithe barn also still survives. Of the abbey church there are substantial remains of the Romanesque paradise (entrance hall). The Gothic choir was converted for use as a Lutheran church in 1739 and still contains many relics of its former use, including a monument to Bernard I, Margrave of Baden-Baden (died 1435, but not buried here). An impressive sculptured panel of the Crucifixion from the abbey was removed from Bad Herrenalb to Schloss Eberstein in the Murg valley in the 19th century.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.
