The St. Ursus Cathedral in Solothurn is dedicated to Ursus of Solothurn, who was a 3rd-century Roman Christian venerated as a saint. His his body is located under the cathedral. The first church on the site was built in the Early Middle Ages. St. Ursus of Solothurn was venerated in the city by the 5th century. By 870 there was a college of canons and presumably a collegiate church in Solothurn. A Romanesque church might have existed, but there is no written or archeological evidence to support or refute it.
The first documented record of the Gothic church comes from 1294, while the altars were ordained in 1293 and 1298. It is likely that the twin towers were damaged in the 1356 Basel earthquake damaged, but there is no reliable sources attesting to the damage. It seems likely, since in 1360 the single Wendelstein tower was built above the church and a gothic facade was added to the west face of the church.
The choir was rebuilt in 1544, while the crypt was re-covered. The nave was rebuilt in 1644 and widened. The sacristy was extended in 1664.
By the 18th century the Gothic church was in a poor condition. On 25 March 1762 the Wendelstein tower collapsed forcing the city to begin planning to replace the building. Paolo Antonio Pisoni (1738-1804) took over construction in 1772. On 26 September 1773 the new church was dedicated by the Bishop of Lausanne. The western facade of the cathedral is a monumental white stone neoclassical structure.
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.
