The Church of St John Aliturgetos is located in Nesebar. The church was not consecrated, hence the name - aliturgetos is the Greek for 'not consecrated'. The legend says that one of the builders fell down and was killed. The church canon did not allow a place where a man had been killed to be used for worship, but according to some records services were held in it.
The church was badly damaged during the 1913 earthquake. Its ruins in the southern part of the peninsula show that it must have been one of the most beautiful medieval churches in Nesebar. It is a domed cruciform church with three altar apses and a narthex. It is 18.5 m long and 10 m wide. The base of the cruciform part of the church is almost quadrangular, shaped by four columns. It has mixed masonry: stone and brick; the facade walls are segmented by blind two-step niches decorated with various geometrical patterns from bricks and stone cubes (ceramic plastic style).
The church was built in the 14th century; it has two entrances, from the north and south, which is rare in the architecture of church buildings.
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.
