Santi Cosma e Damiano was originally a Roman Catholic church affiliated with an Augustinian convent, it is now Greek Orthodox church.
Of the 12th-century Romanesque construction, only the bell-tower remains; the present facade and interiors mainly date to a reconstruction in the 18th century. The main altar (18th century) in polychrome marble has statues by Antonio Callegari and altarpiece by Giambettino Cignaroli and a 16th-century Ark of St Tiziano. Adjacent to the church is a 15th-century cloister. In 1923, at the instigation of a local poet Angelo Canossi, the names of the Italians who died in the war were inscribed in the columns.

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.
