The construction of the Greek Byzantine-style Cathedral of Saint Andrew began in 1908 under the supervision of the architect Anastasios Metaxas, followed by Georgios Nomikos. It was inaugurated 66 years later, in 1974. It is considered the largest Orthodox church in Greece and the third largest Byzantine-style church in the Balkans, after the Cathedral of Saint Sava in Belgrade and Alexander Nevsky Cathedral in Sofia. Over the central dome there is a 5-meter-long, gold-plated cross and over the other domes, there are 12 smaller crosses. These crosses symbolize Jesus and His apostles. The interior of the church is decorated with Byzantine-style wall paintings and mosaics.
Relics of the apostle Saint Andrew are stored in the church. They consist of the small finger, part of the top of the cranium of the Apostle, and small portions of the cross on which he was martyred, all kept in a special shrine. The holy skull of the Apostle was sent there from St. Peter's Basilica, Rome in September 1964, on the orders of Pope Paul VI. Cardinal Bea led the party of 15 cardinals that presented the relic to Bishop Constantine of Patras on 24 September 1964. Thousands of people (among them prime minister Georgios Papandreou) and many Greek Orthodox bishops participated in the reception ceremony of the skull. After a procession through the streets of the city, the skull was placed in a special silver miter inside the church. The cross of St. Andrew was taken from Greece during the Crusades by the Duke of Burgundy. Parts of the cross were kept since Middle Ages in the church of St. Victor in Marseilles. They were returned to Patras on 19 January 1980. The cross of the apostle was presented to the Bishop of Patras Nicodemus by the Roman Catholic delegation led by Cardinal Roger Etchegaray.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
