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.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
