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:
The Château d'Olhain is probably the most famous castle of the Artois region. It is located in the middle of a lake which reflects its picturesque towers and curtain walls. It was also a major stronghold for the Artois in medieval times and testimony to the power of the Olhain family, first mentioned from the 12th century.
The existence of the castle was known early in the 13th century, but the present construction is largely the work of Jean de Nielles, who married Marie d’Olhain at the end of the 15th century.
The marriage of Alix Nielles to Jean de Berghes, Grand Veneur de France (master of hounds) to the King, meant the castle passed to this family, who kept it for more than 450 years. Once confiscated by Charles Quint, it suffered during the wars that ravaged the Artois. Besieged in 1641 by the French, it was partly demolished by the Spaniards in 1654, and finally blown-up and taken by the Dutch in 1710. Restored in 1830, it was abandoned after 1870, and sold by the last Prince of Berghes in 1900. There is also evidence that one of the castles occupants was related to Charles de Batz-Castelmore d'Artagnan, the person Alexandre Dumas based his Three Musketeers charictor d'Artagnan on.
During the World War I and World War II, the castle was requisitioned first by French troops, then Canadian and British soldiers. The current owner has restored the castle to its former glory.
