Brno Ossuary is an underground ossuary. It was rediscovered in 2001 in the historical centre of the city, partially under the Church of St. James. It is estimated that the ossuary holds the remains of over 50 thousand people which makes it the second-largest ossuary in Europe, after the Catacombs of Paris. It's been opened to public since June 2012.
A three-chamber crypt was established under the paved floor of St. James’ Church for these purposes probably in the 17th century. At the beginning the crypt filled slowly, but from the mid-18th century two large symmetric walls of remains from emptied church sepulchres were gradually built there. The rapid filling of the charnel houses was partly due to frequent plague and cholera epidemics that literally decimated the population. The ongoing lack of space for bones from emptied graves required that the charnel house be extended in 1741. The best solution appeared to be the extension of the new ossuary under the cemetery and its connection to the church crypt. The new ossuary, however, was filled in six years and the town council began to discuss its further extension with a connection to the Chapel of the Dead near the church. However, the construction of the connecting corridor was prematurely terminated in the middle of its originally planned length, and thus the original plan has never been implemented.
When both the crypt and the ossuary under the cemetery were full, the entrance staircase from the main nave of the church was sealed with a Latin-inscribed stone slab. Josephine reforms in 1784 led to abolishing the church cemetery for hygiene reasons. The remains from the graves were placed in the crypt, the cemetery walls were pulled down, and the area around the church was paved with unnecessary tombstones. The ossuary, its size, and location fell into oblivion after some time.
In 2001 an archaeological and underground survey was carried out before starting the renovation of the Jakubské square, and its findings were a great surprise. Several pilot bore holes to the depth of four metres confirmed the existence of a large burial complex. The individual rooms were filled with huge volumes of human bones often up to the vault arches. The estimated number of people buried there exceeded 50 thousand. The anthropological analyses carried out so far have shown that the bones of the victims of mediaeval plague and cholera epidemics, as well as those of the Thirty Years’ War and Swedish sieges were placed in the ossuary.
The accumulated humidity and mould, if left untreated, would cause the gradual decomposition of bones and the collapse of the vault less than two metres under the busy roadway of the Jakubské square. That is why the only way to preserve this unique monument was to renovate the ossuary and open it to the public. During the refurbishment, all remains were collected, cleaned and returned to their last resting place. Together with other archaeological finds, the exhibition shows the way of burying in one of the largest city cemeteries in Brno.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.
