Santa Cristina is a Baroque style, Roman Catholic church located in Turin. It mirrors the adjacent church of San Carlo and faces the Piazza San Carlo. The arrangement recalls the twin churches (chiese gemelle) of Santa Maria dei Miracoli (1681) and Santa Maria in Montesanto (1679) facing the Piazza del Popolo in Rome.
The original layout was designed in 1620 by the architect Carlo di Castellamonte, and construction pursued until 1639. The project was only completed between 1715 and 1718, under the guidance of Filippo Juvarra, including the facade elaborately decorated with ovals and details with statues of saints and allegories of the virtues. The adjacent convent housed nuns of the Order of the Discalced Carmelites. In 1802, the order was suppressed in Turin by Napoleonic forces. The interiors were modified in the 19th-century and after the bombardments of World War II.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
