Avioth has been a place of pilgrimage since the early 12th century and it was this that led to the building of the vast Church of Our Lady of Avioth. It is a masterpiece of Flamboyant Gothic architecture, dating from the second half of the 13th century, and is often described as 'lacework in stone'. It is famous for its Recevresse, a unique work of Gothic art. We know it used to receive offerings from the pilgrims, but the reason for its construction remains uncertain.
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.
