The church of San Giuliano is one of the oldest places of worship in Erice, dedicated to San Giuliano, martyred in 254 AD. Its construction was commissioned, according to tradition, by the Norman Grand Count Roger in the 11th century, but it has been a place of worship already during the first centuries of Christianity. It was rebuilt between 1612 and 1615, more imposing and with three naves. In 1927 it was closed due to a collapse and reopened after almost 80 years in 2005.

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.
