Lyon Cathedral was founded by Saint Pothinus and Saint Irenaeus, the first two bishops of Lyon. The cathedral is also known as a Primatiale because in 1079 the Pope granted to the archbishop of Lyon the title of Primate of All the Gauls with the legal supremacy over the principal archbishops of the kingdom. It is located in the heart of the old town, less than five minutes away from the banks of the Saône river, with a large plaza in front of it and a metro stop nearby providing easy access to and from the city center.
Begun in the 12th century on the ruins of a 6th-century church, the cathedral was completed in 1476. The building is 80 meters long (internally), 20 meters wide at the choir, and 32.5 meters high in the nave. The cathedral organ was built by Daublaine and Callinet and was installed in 1841 at the end of the apse and had 15 stops. It was rebuilt in 1875 by Merklin-Schütze and given 30 stops, three keyboards of 54 notes and pedals for 27.
Noteworthy are the two crosses to right and left of the altar, preserved since the council of 1274 as a symbol of the union of the churches, and the Bourbon chapel, built by the Cardinal de Bourbon and his brother Pierre de Bourbon, son-in-law of Louis XI, a masterpiece of 15th century sculpture.
The cathedral also has the Lyon Astronomical Clock from the 14th century.
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.
