The Apollinariskirche is a church on the site of a Roman temple on the Apollinarisberg, a hill above the German town of Remagen. That hill was known as the Martinsberg in the 5th and 6th centuries, presumably after a Frankish chapel there dedicated to Saint Martin, patron of the Franks. In the 9th century this chapel was replaced by a Romanesque church.
In 1110 the Benedictines of the Michaelsberg Abbey, on the initiative of the people of Remagen, set up a provost there. The relics of Saint Apollinaris of Ravenna probably arrived on the mountain at the end of the 14th century, since a pilgrimage to the Apollinarisberg is recorded in 1384. The sarcophagus is the main relic in the 14th century crypt of the church.
A new Neo-Gothic church was built on the site from 1837 to 1852.
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.
