The Church of the Holy Saviour or Sveti Spas in the UNESCO World Heritage town of Nesebar, Bulgaria, is a 17th-century church building, 11.70 m long and 5.70 m wide, consisting of a single nave and apse.
Although small, it is notable for its early 17th century wall paintings representing scenes from the Life of Christ and the Holy Virgin, with a painting of the Virgin Platytera in the apse.
The tombstone of the Byzantine princess Mataissa Cantacuzina, formerly here, is now in the Nesebar Archaeological Museum. The church itself is de-consecrated and is also used as a museum.
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.
