Aquileia, one of the largest and wealthiest cities of the Early Roman Empire, was destroyed by Attila in the mid-5th century. The patriarchal basilica, an outstanding building with an exceptional mosaic pavement, played a key role in the evangelization of a large region of central Europe.
The architectural development of the Basilica of Aquileia, dedicated to the Virgin Mary and the saints Hermagora and Fortunatus, started immediately after 313 AD. In that period the Edict of Milan put an end to religious persecution and the Christian community was legally able to build its first place of public worship. In the following centuries, after the destruction of this first church, seat of a bishopric, the inhabitants of Aquileia built it up again other four times, using each time the structures of the previous buildings: Theodorian Hall, first half of the 4th century; Post-Theodorian North, middle of the 4th century; Post-Theodorian South, end of the 4th century or after the middle of the 5th century; hall of Maxentius, 9th century; Poppo's church, first half of the 11th century; rebuilding of the upper part of the church by Markward von Randeck, from the pointed arches to the roof, 14th-15th century.
The Basilica, as it is today, is in Romanesque-Gothic style. The entire floor is a wonderful coloured mosaic of the 4th century, brought to light in the years 1909-1912. With its 760 square metres the floor is the largest Paleo-Christian mosaic of the western world. The mosaic was partly damaged due to the construction of the columns flanking the right side at the end of the 4th century according to some scholars and after the middle of the 5th century according to others.
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.
