Basilica of Santa Lucia Extra moenia is a Byzantine church built (after Norman rebuilt), according to tradition, in the same place of the martyrdom of the saint in 303 AD. The current appearance is from the 15th–16th centuries. The most ancient parts still preserved include the portal, the three half-circular apses and the first two orders of the belfry. Under the church are the Catacombs of St. Lucy. For this church Caravaggio painted the Burial of St. Lucy, now housed in the Church of Santa Lucìa alla Badìa.
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.
