The church on the site of current San Dalmazzo is documented from the 11th century, but the present church was reconstructed in 1702. In 1885 the interior was redecorated in neo-gothic style. Adjacent to the church is the former convent and school of the Barnabite order. From 1271 to 1606, the church had been linked to the Order of Canons Regular of Sant'Antonio of Vienne, but then was transferred along with the convent to the Barnabites.
The nave was painted by Enrico Reffo in 1895–1916. The interior also contains 18th century canvases and an antique baptismal font.
Between 1629 and 1631 the chapel of the Madonna of Loreto was built, imitating the Casa Santa (Holy House), which contains an icon related to Marian Apparitions.
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.
