Sant'Angelo was constructed in the mid-16th century by the Spanish general and Governor Milan Ferrante Gonzaga, over an edifice already existing in 1418, in replacement of the eponymous one, which had been destroyed to build the new walls. The design was by Domenico Giunti. The small bell tower was added in 1607, while the façade was finished only in 1630, in late-Mannerist or early-Baroque style. The church is one of the few in the city which was not restored in 'neo-medieval' style during the 19th century.
It has a single nave with side chapels and barrel vault, a transept and a deep presbytery. Artworks include works by Gaudenzio Ferrari, Antonio Campi, Morazzone, Simone Peterzano, Ottavio Semino, Camillo Procaccini and Giulio Cesare Procaccini. The triumphal arch has a frescoes with a solemn Incoronation of Mary by Stefano Maria Legnani.
In the transept is the tomb of Blessed Beatrice Casati, the wife and widow of Francino Rusca, the Earl of Locarno. She raised four children -- three sons and one daughter, the latter of whom placed this monument to their mother -- and was a devout member of the Franciscan tertiaries. She died in 1490.
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.
