St. Nicholas Cathedral is the primatial cathedral of the Orthodox Church in America. The original parish church was founded in 1930 as the Russian Orthodox Church of Saint Nicholas. In 1949 the Synod of Bishops authorized the parish to be the church's National War Memorial Shrine and a national campaign to build a monumental Orthodox church in the capital of the United States was begun. The property upon which the cathedral is built was purchased in 1951. The substructure (basement) was completed in 1954 and was used for church services until the superstructure was completed in late 1962. A bell tower commemorating the millennium of Christianity in Russia was dedicated in 1988.
The cathedral architecture is based on the 12th century St. Demetrius Cathedral of Vladimir, Russia. Beginning in 1991, dedicated iconographers from Moscow led by Alexander Maskalionov painted icons throughout the nave in the traditional style. This work was completed in 1994.
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.
