The Cathedral of Saint Peter of Beauvais is, in some respects, the most daring achievement of Gothic architecture, and consists only of a transept (16th-century) and choir, with apse and seven polygonal apsidal chapels (13th-century), which are reached by an ambulatory.
A small Romanesque church dating back to the 10th-century, known as the Basse Œuvre, still occupies the site destined for the nave of the Beauvais Cathedral.
Work was begun in 1225 under count-bishop Milo of Nanteuil, with funding of his family, immediately after the third in a series of fires in the old wooden-roofed basilica, which had reconsecrated its altar only three years before the fire; the choir was completed in 1272, in two campaigns, with an interval (1232–38) owing to a funding crisis provoked by a struggle with Louis IX. Under Bishop Guillaume de Grez, an extra 4.9 m was added to the height, to make it the highest-vaulted cathedral in Europe. The vaulting in the interior of the choir reaches 48 m in height, far surpassing the concurrently constructed Cathedral of Notre-Dame in Amiens, with its 42-metre nave.
The work was interrupted in 1284 by the collapse of some of the vaulting of the recently completed choir. This collapse is often seen as a disaster that produced a failure of nerve among the French masons working in Gothic style; modern historians have reservations about this deterministic view.
However, large-scale Gothic design continued, and the choir was rebuilt at the same height, albeit with more columns in the chevet and choir, converting the vaulting from quadripartite vaulting to sexpartite vaulting. The transept was built from 1500 to 1548. In 1573, the fall of a too-ambitious 153-m central tower stopped work again. The tower would have made the church the tallest structure in the world at the time. Afterwards little structural addition was made.
Its façades, especially that on the south, exhibit all the richness of the late Gothic style. The carved wooden doors of both the north and the south portals are masterpieces, respectively, of Gothic and Renaissance workmanship. The church possesses an elaborate astronomical clock in neo-Gothic taste (1866) and tapestries of the 15th and 17th centuries, but its chief artistic treasures are stained glass windows of the 13th, 14th, and 16th centuries, the most beautiful of them from the hand of Renaissance artist Engrand Le Prince, a native of Beauvais. To him also is due some of the stained glass in St-Etienne, the second church of the town, and an interesting example of the transition stage between the Gothic and the Renaissance styles.
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.
