Lillebonne is located on the north banks of the Seine River. From the first to the third centuries AD the town, then called Juliobona by the Romans – a homage to Julius Cesar, was a very prosperous port. The relatively well preserved Roman amphitheatre (capable of holding 3,000 persons) and baths are all that remains from these times. Many Roman and Gallic relics, notably a bronze statue of a woman and two fine mosaics, have been found and transported to the museum at Rouen. The Roman town was abandoned at the end of the third century when it was invaded by barbarians.
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.
