The Holy chamber of Oviedo (Cámara Santa de Oviedo) is a pre-Romanesque church built next to pre-romanesque Tower of San Miguel of the city's cathedral. Nowadays, the church occupies the angle between the south arm of the cathedral transept and a side of the cloister.
It was built during the 9th century as a palace chapel for King Alfonso II of Asturias and the church of San Salvador of Oviedo. Apart from acting as royal chapel, the Holy Chamber was built to house the jewels and relics of the cathedral of San Salvador in Oviedo, a function it continues to have 1200 years later. Some of these jewels were donated by the Kings Alfonso II and Alfonso III, and represent extraordinary gold artifacts of Asturian Pre-Romanesque, brought from Toledo after the fall of the Visigothic kingdom.
Consequently, the cathedral of Oviedo was also called Sancta Ovetensis; owing to quantity and quality of relics contained in the Cámara Santa. The Holy Chamber remains as the only sample of the early medieval complex. It was built as a relics' room to keep the different treasures associated with the Kingdom of Asturias (Cross of the Angels, Victory Cross, Agate box, Arca Santa and Sudarium of Oviedo), brought from Jerusalem to Africa, and after several translations was finally deposited at Oviedo by Alfonso II of Asturias.
It was declared a World Heritage Site by UNESCO in December 1998.
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.
