Santa Barbara church was built in 1757 for the Convent of the Salesas Reales, housing nuns belonging to the order of St. Francis de Sales. The convent was founded in 1748 by the Queen Bárbara de Braganza, wife of Ferdinand VI of Spain. The church, which stood next to the convent, was designed by Francisco Carlier in collaboration with Francisco Moradillo. In 1870, the monastery was closed, and the government used the monastery as the Palace of Justice, now as the Supreme Court. In 1891, the church was open to parish worship.
The exterior is noted for the statues of St. Francis de Sales and St Jeanne de Chantal, founders of the Order, sculpted by Alfonso Giraldo Vergaz. In the interior, are the burial tombs of Ferdinand VI and his wife. These were commissioned by Charles III of Spain and completed by the architect Francisco Sabatini and the sculptor Francisco Gutiérrez.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
