Auxerre Cathedral is known for its expansive stained glass windows. Most of the Burgundian Gothic cathedral was built between 1215 and 1233 above an 11th-century crypt. Construction continued until the 1540s when the cupola, in Renaissance style that takes the place of one pinnacle on the completed tower, was completed. The first building campaign erected the chevet at the liturgical east end, followed later in the century by a new façade and the bases of new towers at the west end (still linked to the apse end by the nave of the old cathedral). Construction on the nave and transepts proceeded slowly throughout the 14th and 15th centuries.
The narrative sculptural program of the portals on the west end are noted for their extent and variety. Guillaume de Seignelay, bishop of Auxerre decided to undertake the reconstruction of the older edifice about 1215, to which he set an example by contributing heavily and consistently from his own resources, and even bequeathed funds after his transfer to the see of Paris in 1220. The chevet was completed by his successor, Henri de Villeneuve (1220–34).
Stimulus was provided about 1270 by Jean de Châlons-Rochefort, who had recently become Count of Auxerre, having supported the Duke of Burgundy against his own brother, by marrying Alix, the heiress of Auxerre. He was the largest fief-holder in the Duchy and commemorated the new status of his fief of Auxerre by enriching the front of its chief ornament, the cathedral, whose Carolingian nave had been erected by his ancestor Hugh de Châlons, 10th-century bishop of Auxerre. Its program of sculpture was carried through long after his death and completed in the early 15th century.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
