Saalkirche, today a Protestant church, was constructed on a cross‐shaped floor in the 10th century as a further sacral building in the Ingelheim Pfalz. Thus the imperial palace reached its closed U‐shaped form, which had already been foreseen in the Carolingian building concept. In the following centuries the church was constantly remodelled, mainly in the 12th century. Integrated into a monastery in 1345, the church overcame the resettlement of the former Pfalz area, the so‐called ‘Ingelheimer Saal’ to which the name of the church refers. Given up in course of Reformation the building became dilapidated. In 1965 its reconstruction was completed. A small exhibition on the Ottonian period of the Pfalz was opened inside in 2004.
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.
