Saint Nicholas Cathedral (officially Cathédrale Notre-Dame-Immaculée) is the cathedral of the Roman Catholic Archdiocese of Monaco, where many of the Grimaldis were buried, including Grace Kelly and more recently, Rainier III.
The cathedral was built in 1875-1903 and consecrated in 1911, and is on the site of the first parish church in Monaco built in 1252 and dedicated to St. Nicholas. Of note are the retable (circa 1500) to the right of the transept, the Great Altar and the Episcopal throne in white Carrara marble.
Pontifical services take place on the major religious festivals such as the Feast of Sainte Dévote (27 January) and the National holiday (19 November). On feast days and during religious music concerts, one can hear the magnificent four-keyboard organ, inaugurated in 1976.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
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.
