The Abbey of St. Jean des Vignes was a monastery of Augustinian Canons situated in the south western hills of Soissons. Only ruins remain, of which the west front is still one of the most spectacular pieces of architecture in the town.
The abbey was founded on St. John's hill in 1076 by Hughes Le Blanc. Initially built in Romanesque style, the first buildings were replaced at the end of the 12th century by those visible today. The west front was begun in the 12th century, although not finished until the 16th. The refectory and cellar date from the 13th century, parts of the cloisters from the end of the 13th century, while other parts are from the 16th century, as is the abbot's lodging.
When the abbey was suppressed during the French Revolution the premises were put to use for military purposes, and an arsenal was added.
The site was acquired by the town of Soissons in the 1970s and the remaining buildings are now occupied by educational and heritage-related bodies.
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.
