The Notre Dame Church Collegiate is considered one of the most beautiful examples of medieval architecture in France. Built between the 11th and 16th century, the collegiate contains different architectural styles. Where the altar and the transept are Romanesque style, the rest of the building was rebuilt in three different Gothic (namely Early, Flamboyant and Perpendicular Gothic) styles. The organs date back to the beginning of the 17th century and which was restored in 1979. Some magnificent abstract-style stained glass windows were inserted in the 1970’s to replace those destroyed during World War II.
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.
