Munsterkerk, built in the 13th century, is the most important example of Late Romanesque architecture in the Netherlands. It was built as part of Cistercian Munster Abbey, a nunnery founded around 1218 by count Gerard III van Gelre.
The oldest part of the church is a choir which was influenced by German cathedrals in Cologne, Speyer etc. The nave was probably built between 1220 and 1244. The church was restored by Pierre Cuypers in second half of the 19th century. The two towers erected during the restoration were damaged by earthquake in 1992.
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.
