The church of Saint Jean de Montierneuf was built in the last third of the 11th century. Supported externally by flying buttresses and pierced by numerous bays, it gives the choir an abundant and unexpected clarity. The original Romanesque chevet of the church of Saint Jean de Montierneuf is largely raised towards the end of the 13th century by a Gothic apse.
The abbey church was seriously damaged during the wars of religion and underwent important restorations in the 17th century, the most obvious of which was the construction of a new façade following the shortening of the nave.
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.
