The Basilica of Saints Nazarius and Celsus is a romanesque-gothic minor basilica, located in the citadel of Carcassonne. The original church is thought to have been constructed in the 6th century during the reign of Theodoric the Great, ruler of the Visigoths.
On 12 June 1096, Pope Urban II visited the town and blessed the building materials for the construction of the cathedral. Construction was completed in the first half of the twelfth century. It was built on the site of a Carolingian cathedral, of which no traces remain. The crypt too, despite its ancient appearance, dates from the new construction.
Around the end of the 13th century, during the rule of kings Philip III, Philip IV, and the episcopates of Pierre de Rochefort and Pierre Rodier, the cathedral was reconstructed in the Gothic style. It remained the cathedral of Carcassonne until 1803, when it lost the title to the present Carcassonne Cathedral.
The Church of Saints Nazarius and Celsus obtained the status of historical monument in 1840. Around this time, the architect Eugène Viollet-le-Duc renovated the church along with the rest of the citadel. In 1898, the church was elevated to a minor basilica.
The sandstone basilica's floor plan is based on a Latin cross, internally measuring 59 m in total length, 16 m in nave width, and 36 m along the transept. The oldest part of the church is the Romanesque tripartite nave. The main entrance in its north wall is formed by a Romanesque portal of five receding arches over two doors. A fortress façade forms the west wall, as is common for medieval Languedocian church buildings.
The transept and choir were rebuilt in the Gothic style. The larger windows in this part of the church permit a better illumination compared to the darker romansque nave. The central stained glass window of the choir from 1280 is one of the oldest ones in the south of France. Together with the upper trefoils (the Resurrection of Jesus and the Resurrection of the dead), it depicts the life of Jesus in 16 medallions.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
