The Church of Saint Sophia in Ohrid is one of the most important monuments of North Macedonia, housing architecture and art from the Middle Ages.
The current church was built on the foundations of a metropolitan cathedral demolished in the first decade of the 6th century by the Barbarian invasions. The next church was built during the First Bulgarian Empire, after the official conversion to Christianity. Some sources date the building of the church during the rule of Knyaz Boris I (852 – 889). It was basically rebuilt in the last decade of the 10th century as a patriarchal cathedral in the form of a dome basilica, after the replacement of the capital of Bulgaria in Ohrid, during the reign of Tsar Samuil, when the church was the seat of the Bulgarian Patriarchate, an autocephalous Patriarchate. Later it became a seat of the Archbishopric of Ohrid, under the Patriarchate of Constantinople until the 18th century.
It was converted into a mosque during the rule of the Ottoman Empire. The interior of the church has been preserved with frescoes from the 11th, 12th and 13th century, which represent some of the most significant achievements in Byzantine painting of the time. The main part of the church was built in the 11th century, while external additions were built by Archbishop Gregory II in the 14th century.
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.
