The Arch of Carpentras is a Roman triumphal arch from the beginning of the first century AD. It has a single fornix, framed by fluted lesenes and decorated with an archivolt of vine tendrils. At the outer corners there are engaged columns. On the sides there are images of trophies flanked by barbarian prisoners. These trophy reliefs are also found on the short sides of the Arch of Orange, which is however more richly decorated.
The arch was originally located on the city's cardo maximus. Later it was incorporated into the old cathedral as an access door and still later into the episcopal palace (now the courthouse).
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.
