The Basilica of St. Severin is one of the twelve Romanesque churches of Cologne. St. Severin was established in the late 4th century as a memorial chapel and extended several times. The oldest parts of today's building date back to the 10th century.
The church has been extended and enlarged several times. On the passable archaeological dig area under the church in the midst of a Roman graveyard the foundation remains of the original building can be viewed.
St. Severin still owns rich furnishing: the murals in the crypta, the choral equipment with a part of the medieval floor, the original choir seating and the high altar, behind which the Shrine to the Holy Severin is shown, so that the believers could walk under it.
The forked crucifix from the 14th century and the late Gothic glass paintings in the long nave are also remarkable. The external impression is primarily Gothic as only the choir chancel remained Romanesque.
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.
