Ursuline Church of the Holy Trinity was built between 1718 and 1726 in the Baroque style. The church was designed by Carlo Martinuzzi, a Friulian architect, and is noted for its extensive altar made of African marble designed by Francesco Robba, who also built the Fountain of the Three Rivers of Carniola which stands on Town Square in Ljubljana. The original bell tower was destroyed in the Ljubljana earthquake of 1895. The current one was built in the 1900s. The staircase in front of the entrance has been partially designed by the architect Jože Plečnik in 1930.
In front of the Ursuline Church stands the Holy Trinity Column. The originally wooden column stood since 1693 in front of a Carmelite monastery at Ajdovščina. In 1722, it was replaced with a stone one, made by Luka Mislej, whereas the marble statues have been presumably created by Francesco Robba. In 1834, the stonemason Ignacij Toman made a new pedestal and the original Robba's sculpture was replaced with a replica. The original is now kept by the City Museum of Ljubljana. The column was again renovated after the 1895 Ljubljana earthquake by the stonemason Feliks Toman. It was relocated in front of the Ursuline Church in 1927 upon plans by Plečnik as part of his redesign of Congress Square. Now it forms an axis with the Ursuline Church, the lights at the square and the building of the Slovenian Philharmonics.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.
