The Carlo al Corso church replaced an earlier church. This church likely designed by Rosario Gagliardi, was part of the town reconstruction after the 1693 Sicily earthquake.
The concave façade has three superimposed orders of columns, identified by their capitals from base to roofline as Doric, Ionic and Corinthian; in the progression expected in classical construction. The third story has floral oculus. The interior has a longitudinal layout with a barrel vault sustained by pilasters. The main altar was rescued from the prior church.
Inside the church, the 18th-century altarpieces display a Sacrifice of Isaac; a Flight into Egypt; a Deposition; San Carlo Borromeo ministering to those ill with the plague; a Virgin and Child with saints; Biblical Scene; St Ignatius of Loyola, founder of the Jesuit order; and wood icon of St Aloyitius Gonzaga, another Jesuit saint. The main altar is flanked by marble statues symbolizing Faith and Hope respectively, sculpted by Giuseppe Giuliano. The nave ceiling is frescoed by Costantino Carasi, depicting the Transfiguration and the Healing of the Paralytic, with a central panel depicting the Triumph of the Agnus Dei. The spandrels that support the dome are frescoed with the evangelists, and just below are four allegorical statues depicting the respective cardinal virtues.
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.
