Yelizarov or Yeleazarov Convent is a small convent founded as a monastery in 1447 by a local peasant named Eleazar. He constructed the wooden church of Three Holy Fathers, wherein he was interred upon his death on 15 May 1481. Eleazar was canonized at the Stoglavy Sobor in 1551.
In the mid-16th century, the monastery was heavily fortified and attained a position of great importance and celebrity, owing to its learned hegumen, Philotheus of Pskov, who is credited with authorship of the Legend of the White Cowl and the Third Rome prophecy. It was during his hegumenship that the monastery became known for its school of icon-painters and its still-standing cathedral was built. Some scholars believe that the only known copy of the Lay of Igor's Campaign was created by one of local monks at the behest of Philotheus.
After seven decades of Soviet neglect, the monastery was revived as a nunnery patronized by Lyudmila Putina and Lyubov Sliska who commissioned a luxurious guest house for their prolonged stays at the convent.
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.
