The village church dedicated to Saint Mary Magdalene in Rennes-le-Château has been rebuilt several times. The earliest church of which there is any evidence on the site may date to the 8th century. However, this original church was almost certainly in ruins by the 10th or 11th century, when another church was built upon the site - remnants of which can be seen in Romanesque pillared arcades on the north side of the apse. This survived in poor repair until the 19th century, when it was renovated by the local priest, Bérenger Saunière.
The village received up to around 100,000 tourists each year at the height of popularity of Dan Brown's bestselling novel The Da Vinci Code. The modern reputation of Rennes-le-Château rises mainly from claims and stories dating from the mid-1950s concerning the local 19th-century priest Father Bérenger Saunière. These stories influenced the authors of the worldwide bestseller The Holy Blood and the Holy Grail in 1982, and that work in turn influenced Dan Brown when he wrote The Da Vinci Code, published in 2003.

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.
