Blois Cathedral (Cathédrale Saint-Louis de Blois) is a Roman Catholic cathedral, and a national monument of France, in Blois. It is the seat of the Bishopric of Blois, established in 1697.
This was previously the collegiate church of Saint-Solenne, the original building of which dated from the 12th century. Apart from some traces in the crypt nothing survives of this. The façade and the bell tower were built in 1544. The nave was destroyed by a hurricane in 1678, and the reconstruction in Gothic style took place between 1680 and 1700 under the architect Arnoult-Séraphin Poictevin (d. 1720). The Lady Chapel by the architect Jules Potier de la Morandière was added in about 1860.
To celebrate the church's elevation to a cathedral in 1697, Louis XIV presented the organ loft in 1704. The new see thereupon took the dedication to Saint Louis.
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.
