The Church of St. Stephen is a former Eastern Orthodox Church in Nessebar, Eastern Bulgaria, which is now turned into a museum. It is part of architectural and historical reserve in the city, which is part of the UNESCO World Heritage Site and one of the 100 national tourist sites. The building consists of a three-nave basilica with dimensions 12.1 x 9.5 m, and served as the cathedral church of the metropolitan center in the province of Nessebar.
The church has been restored and enlarged several times and is difficult to be dated exactly. The eastern part is the oldest and probably dates from the 11th century. Some centuries later the church was enlarged by adding a new structure to the west. The western wall was demolished and the present narthex was built. The church was timber-roofed. The exterior is rich in design. The eastern and the western façades are crowned with pediments in the form of trefoil arches. The eastern façade is more elaborate. It comprises three high apses, the middle of which rises above the side ones. All three are decorated with ceramic plaques. A colourful effect is achieved by the mixed masonry of stone and bricks, without keeping to any fixed pattern. The decoration of the façade is the reason for defining this church as an example of the ornamental architectural style.
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.
