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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
