Lin is situated on a small peninsula on Lake Ohrid. The Lin area has been inhabited since at least the Iron Age. Archaeological findings from the hilltop above the present-day village include foundation walls and mosaics of an early Christian Byzantine church, dating from the 6th century. The church is included within the possible UNESCO site of the Natural and Cultural Heritage of the Ohrid Region.
The ruins of the paleo-christian church of Lin together with its floor mosaics from the 4th-5th century reveal the presence of Christianity.
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.
